In this video, James Conrad explains what a proxy server is and the five main reasons for implementing a Proxy Server. Learn more about proxy server basics and start a free week of training with CBT Nuggets today.
A proxy server can make your network safer, faster, and more reliable thanks to five main functions.
First, a proxy can obscure client IP addresses. Also, it can block malicious traffic. Third, a proxy server can help block sites you or the company don't want visited. On top of that, a proxy can log the activity of users. And fifth, performance can be improved with a proxy.
These aren't the only five features of a proxy server, but they're the most obvious examples of what a proxy server can do for your network.
In all cases, the primary job of the proxy server is to take the traffic on the internal network and swap out its IP address for a public address when that traffic goes out to the Internet. The different methods and safeguards it has are where the five features that James explains come from.

3:40: Blocking selected sites

[@datpspguy]

Great video, I liked the funny stories you added in to make it all come together. Thanks!!

[@1DJLNR]

i love the humour and jokes in this video, i always come back for just that as i know all of this well before youtube existed, i like to watch tutorial vids to pass on so i am not the only one talking around many friends, yes we geeks talk about many things where others who have no tech background talk about other people's business or simply say nothing..

[@allisongray7344]

Great illustration! It’s very creative. Proxy servers have many advantages. I have been using Instantproxies for a couple years now.

[@abdullahnsy]

[@Qweekedit]

[@joyl2981]

Thank you. I learned a lot from this, including why a proxy is really quite closer to part of an online privacy routine, whereas a VPN is better for what I'm looking for!

[@williamnguyen2392]

I thot routers already create a public IP for the network....or do routers nowadays just also serve as a proxy server?

[@Crunkjuic]

thanks!!

[@leonardobilic1079]

0:40 "I'm not gonna tell you which one of these she selected", at the same time marks the "No" xD I am really sorry for you dude and certainly more sorry for her. She let pass a cool guy with a decent humor haha. Good explanation of proxys thanks for that! :)

[@IPlayGamezHD]

Well so if we use a proxy server there is no need to use nat on my internet edge router?

[@douwedevries8725]

You are amazing.

[@solomond.4012]

Tanks man

[@rainmared]

thanks

[@jeroenfigee]

Brilliant ! :-)

[@johnconnor9787]

am I write thinking that the first in the list - Obscure client IP, works with the same logic as NAT?

[@MattBassNGuitar]

What do you do if your proxy is refusing connections to every single site?
