Thanks Pranab. Do check out other videos on our channel and share if you find them helpful..
First off, your videos are really easy to understand and even better then paid courses. Thanks a lot. NACLs are stateless, which means we have to define both inbound and outbound rules. In the example you showed, you only opened port 80 for inbound. Can you also cover the significance of outbound rules? It worked in this case you most likely have the default ALLOW ALL for outbound. thanks
Thanks a lot. Yes, I will cover that scenario in a new video. Please do share our video with your friends

Hello Great demo - excellent - one observation though. You could go a little slow on the Key part. That was too fast. I am aware of the time limit, but that is an important topic. Again great video. Keep doing it - I am following you. Thank you.
there is a detailed separate video only on that part .. please check that one.
To the point explanation. Easy to understand. 1 question around NACL- does it go through all traffic rules defined before allowing or denying any traffic? I understand it does so in chronological order.
may be try it out and check it..
hi sir
Nice Explanation..
i have one question, 2 instances launched in one subnet in one service is running with some "x " port which is not opened in security group of that instance, now can i able to access that service from my second instance?
it has to be opened in security group surely even if they are in same subnet. watch my video on Security groups please.
Please do make a video on NACL so we can understand it better
Thanks for the video again, can You please explain the ephemeral ports of Nacl's and their importance on private servers. For example, what are the best practices of Inbound and Outbound rules of Nacls' and the port association when I had my DB server in private subnet.
Typically, you would add a DENY rule on NACL, if you want to block some traffic at boundary level.
Ephemeral ports information is given in AWS documentation, please refer once. Look at some LIVE videos playlist, you will have lot of info there.
Ephemeral ports - there are organizations that run application on different ports, suppose there is a company "A" and company "B" both are using same application but on different port number, so in that case if we need to allow everyone (outside) to access the application of both these companies A and B, in that case either we can allow the port numbers for these application or we can use Ephemeral port in case we don't know the exact port number for these application........I hope u got my point
Hi, As per the session, when i was trying to create a 2nd EC2 instance. it didn't allowed me to create another, please let me know the reason behind
very good video..pls upload some video on Route 53..spent one month still cnt understand route 53...pls upload video thanks in advance
Jon Punia okay sure. will do a video on Route 53 soon. remain updated and let me know any other requests..
Hello Knowledge India,
Thanks for sharing this useful video with us!
I have one simple question. Today, we have firewalls (stateful) that by default allows the return traffic where request was originated so we don't need to allow return traffic/enable rule to do so. Is network ACLs are something that by default allows the return traffic to users?
just would like to confirm my understanding. I have see at the end you deleted the outbound ACL and still it works fine. I mean server still serving the requst to user.
Thanks.
NACLs are stateless hence on the other direction as well, you need to have the rules. Please read/watch again and you would be clear. Please do not forget to share if you learned something from this video. Also, please let your friends know about the upcoming AWS Live training on weekends. Thanks a lot.
Thank you so much, Sir! Superb videos one small request will you arrange them in an order and paste the link over here sir so it will be helpful to us to access easily.

My IIS server wont load up on the public instance, what could be the issue? after installing the IIS I simply copy and paste the public IP address of the ec2 instance on any browser?
Hi, i created an instance but it does not have a public DNS hostname, i enabled the dns hostnames, attached it to the correct subnet with igw but it still shows that i have a public ip.. how do i resolve this?
Question: at 14th minute as you added rule 50 to explicitly DENY the traffic on HTTP port 80 on INBOUND side, if you we'd have added the same line on OUTBOUND side as rule 80, the result will be same (internet access will not be there from browser)
Does my understanding right?
I suggest you should read the concept of Ephemeral Ports in case of NACL. Also, please see my video on Security Groups.
I noticed you did not enable ip address while creating your private EC2 instance.Can you SSH into your instance without a public IP?
When you get into private machine it opens all together in a seperate RDP connection, how do we acheive that?
Very useful video..thanks..During the video there was also mention of link (video to) to Security Groups..Can i request that link here. thanks
ua-cam.com/video/k5yvD4ykPcI/v-deo.html
@@knowledgeindia Thank you Sir...I am sitting home alone and and just clapping for you for the wonderful knowledge shared so easily. I have already subscribed and and have been proud to share these with my knowns. Thank you Sir.
For NACL, if I deny inbound traffic on port 80 with the lowest rule number, but allow all outbound traffic, will the public instance be able to access google.com in its browser, or will it be inaccessible?
Inaccessible as NACL is stateless.. Also, such scenarios you should do yourself and check as well.
good video
what is the different between security group and network acl?
Look at our live videos, this is discussed with examples.
Hi sir thank you for sharing the knowledge to everyone,
By watching the videos i have done the same set of configuration 4subnets, 2private, 2 public, I am able to login to public instance,And through public i instance only for the first time i was able to login to the priavte instance, later after installing IIS. If i enter the credentials getting "access denied".please help me
check the security group of private instance. Else, may be create a new private instance.

yes.. it will be charge back
Question is on Bastion host vs Nat instance/NAT gateways .
NAT acts as a interface to connect the private subntes to internet ,
BATION though doesnt do that , It helps to manage the EC2 instances in private subnet from public subnet [ is my understanding correct ? ]
and the questions is
offlate, As NAT interface are getting replaced by NAT gateways , Does NAT Gate way has the ablity to play bation hosts too ?
You understanding is right.
No NAT Gateways would not do the work of Bastion Host/Jumpbox. NAT Gateway is a manged service and you do not get to login to it.
In such a case, you need to create a small Linux/Windows Machine as Bastion host in Public subnet.
Hello KI,
Need assistance on below
I was practicing NACL and below is the lab set up
1.Installed Apache in public subnet on Amazon EC2
2. Security group- added 2 rules for SSH, HTTP
3. able to connect to Apache over internet with public IP of EC2 instance.
4. In default NACL, added rule 99 to deny traffic on port 80 from Internet.
This should block my connectivity to Apache server but I can still access the index page
Not sure what I have missed. Can you please suggest?
1. check if apache is running on port 80 only.
2. see if default NACL is associated to the subnet where your EC2 is.
Join our linkedin group surely -- www.linkedin.com/groups/10389754 , it would be great to ask these questions in the group.
Sir, Thank you for quick response.
2nd point I have verified. Let me recheck on what port Apache is running.
Already part of our Linked group.😄 Thought it will be good if I comment below the NACL video.
Thanks
I was just wondering, is this not similar to Bastion Hosts? The first Machine acts as the host, right?
You are right functionality wise. Check our networking playlist and this video
ua-cam.com/video/hADsoPODtVQ/v-deo.html
My question is simple. In NACL, Do we need to allow/deny the same IPs in outbound rules which we allow/deny in inbound rule????
Thanks in advance sir.
Raju Konduru yes
At 3:40 , (looking at "Description" for selected "public-EC2" instance) this public instance has Private DNS, Private IPs, Public DNS and Public IPs whereas for " private-EC2" instance has Private DNS and Private IPs only. I am a little confused as to why public instance has Private DNS, Private IPs. Please tell.
Private IP is a must and would be there with every instance always. Public IP is optional.
@@knowledgeindia thank you
Can you please describe theoretically from 12:12 ie inbound and outbound rules, Thanks in advance.
How within VPC one public instance(public subnet) is able to talk to private instance(private subnet) ? then what is the benefit of creating two security group?
My question is - if hacker hacks public instance then he can easily access private as it is accessible from any instance within VPC ??
The Private instance is accessible because the Private subnet is attached to NAT Gateway. Now answer to your question is "YES", if hacker hacks public instance then he can easily access private instance as all these are withing in one VPC and connected with each other.....
Sandeep, please give a solution to the Rakesh question, this is very important! while setting up network and security for Web Apps hosted at AWS, what is the best way, would you suggest to minimize the impact?
@dimple-You wouldn’t open up the whole private subnets to the public subnets. You would modify sgs and nacls in such a way this exposure is reduced. This was an intro to how and why communications happen. It’s up to you to figure out ways to mitigate risks. @sandeep- thanks for the videos. Great work!
Its very well & good to understand the concept.
But Your Public Machine having IP 10.0.0.41 at back end. & your private machine having 10.0.0.14 ; So it will be easier to browse the IIS from private.
I have LAN network 172.16.0.0 series (4 machine) & have Internet series 192.168.1.0 (1 macine ). I have AWS instance & need to make connectivity in between 172.16.0.0 & AWS EC2.
Will it possible ? & how?
I could not get the deployment layout completely. For further connect we will have to look at it individually. would be happy to get into consulting mode, if you org has a requirement. Please let me know.

7 to 11 am IST. i am sorry, but the best price is already quoted.
The private instance is in AZ-a where as NAT gateway is in AZ-C. How does traffic gets routed from private instance in AZ-a to outside NAT GW in AZ-c?
Because of the route table entry.. see that again please
Hi, Your Videos are very clear and worth to watch. I Appreciate it. And You owe me over 8 hours for keeping me attached to your channel in understanding AWS.
I just need your comment on my implementation
I created 2 Public and 2 Private Subnets
And I don't want to open up my SSH port to the Public Facing Subnets so I just created NACL's
Having said that, In order to connect to my Array of Public and Private Instances i created a "Public-Dev" interface which has SSH & RDP Port Opened up. Am planning to SSH into the Public-Dev Instances and then from Inside that I wanted SSH to my Public facing Subnet Instances
Is this Right ? is it how it should be done ?
Is there an better way ?
Appreciate your comments. And Keep up the good Work.
Liked, Shared and commented :)
Thanks for your kind words. I hope to give knowledge to people who appreciate it.
What you have proposed above is okay, but a small correction.
Keep 2 Public and 2 Private subnets. Put your instances (web server) in private subnets. Put an ELB in Public subnets which will accept web traffic from internet and pass it on to the instances (web server). Allow only web ports (80 / 443) on webservers from ELB SG.
Also, keep a small instance in Public subnet and open 22 or 3389 on this machine from Anywhere. This will act as Bastion Host or Jumpbox. You will login to this instance using its public IP first and then you can use Private IP of server to login into that private instance. Ensure to open port 22 or 3389 of private instances to Bastion host security Group.
I highly recommend looking at this tutorial, to view the architecture -- ua-cam.com/video/G67TaU4qSYE/v-deo.html

what is port range means i didnt got that ? can you please explain it

Hi, i am able to log in to the public ec2 and then to private ec2, but i private ec2 my internet explorer is not working. It asks me to try about from different user! What might be the issue?
The security group of the private instance does not allow outbound traffic for the internet to be accessible.
Hi Sir, these videos are very thorough and useful, thank you. I've recently made a wordpress website(LAMP stack) using aws with separate EC2 instance(for web app) and MySQL RDS(for storage) instance. It was running smooth until I stopped the EC2 to assign an Elastic IP. Now the website is not opening over the internet. I logged into the EC2 server and tried to connect to my RDS over the terminal using "mysql -h hostname -P 3306 -u username -p", it worked and I could access the RDS from my EC2(as the private IP of EC2 remained the same). However, the new public IP/DNS is no longer working over the internet and my website is not accessible now...Pls help me out, thanks.
Surya Rao
Here are the steps. please check if the website opens up on private IP of EC2, while you are logged in to the machine.
if yes, then check the security group & NACL.
SOMETIMES, a particular elastic IP would be blacklisted at many places. can you try attaching a new elastic IP and try again.
if nothing of this works, I shall help you over screen share..
Please see this video, it might help you further --
ua-cam.com/video/iZibF-P4Utc/v-deo.html
Dear Sir, thanks a lot for the replies. My EC2 is an ubuntu AMI with LAMP stack installed in it. I'm using the mac terminal to connect to the instance. Through that instance, I'm able to connect to my MySQL RDS as well but I'm not able to open the website in the browser. My Security group in-bound rules are SSH-22, HTTP-80, HTTPS-443, MySQL/Arora-sg-*** enabled. Outbound rules are ALL ports allowed. NACL setting are default(Rule-100) on the below subnets. I also tried changing elastic IPs but that didn't help.
VPC(172.31.0.0/16)
subnet-52dbcb18 (172.31.0.0/20), subnet-0a2fff63(172.31.16.0/20)
I also noticed that when I use the public dns of EC2 in the browser, it's changing to the old Public dns on its own. I think RDS has stored that old Public IP
have you applied same Security group to EC2 and RDS. If so, make it 2 separate SG and open only required ports.
ensure that your website is running on port 80 and in SG port 80 is open to Anywhere.
check your IGW and route table for the Subnet where your EC2 is located.
One basic question - When the private instance accesses the internet, the request is going out first. So, if you were to block the outgoing NACL, the result would be the same i.e. page not loaded?
yes
try it as well. it would be good.
It feels like we can achieve everything with security groups. What would be a good use case to use ACLs in conjunction with security groups?
If you want to deny a range of IPs which are abusing your website or trying to attack, you can add DENY rule at NACL level.
Great. Thanks. That looks like a good use case. I was going through documentation and it looks like ACLs apply at subnet level and security groups apply at instance level. Did I get that right?
yes that's right. So, anything which needs to be blocked for all the instances - do that at Subnet level (via NACL).
Thanks a lot man. This is very helpful.
Please make a series for certification .
please check our playlists for the same..
Hello Sir,
How can I restrict the outbound port for a specific service ...like I want that one of my instances can only send traffic to the internet via port 25 only ..how is that possible ?
Why not. Look at the Outbound rules of Security Group of that instance. Delete all rules there and add only one rule. TCP 25 0.0.0.0/0
Knowledge India Thank you.. but can I use any rule it in the network ACL itself... will it be a good approach?
In case of outbound in NACL, ephemeral ports come into picture and hence figuring a port becomes tricky. You can use NACL for Inbound restriction. Don't use for Outbound. If you know a fixed IP (or range) use that in NACL outbound. E.g. TCP ALL ports 23.45.25.46/32
