Best video I've found! I was struggling the last few hours and watched multiple videos and read multiple how-tos. I should have found your video first! 11 minutes and I was done and successful! Thanks, man!
Dude you're a rockstar....I've been watching your videos and they've been very helpful with me setting up my proxmox home lab. Please keep up the great work and don't stop!
Awesome Video! I’ve always struggled with the Proxmox Wiki, but thanks to this video, I finally understood how firewall rules work in Proxmox right away. Thank you for creating this video! I’d be thrilled to see more videos on the topic of Proxmox. I’ve already hit the subscribe button and the notification bell! 😊👍
Thank you for a great video. We have virtualized the compute and storage but virtualization of network is still pending. And there is not any authentic video content on it. Kindly make a video on SDN.
Actually it does work, it just doesn't block port 8006 (Web UI) and 22 (SSH) if requests are coming from you local network. If I'm not mistaken, Proxmox devs did that because people kept locking themselves out of their own servers and complaining about it. Plus, it's a much more elegant way of doing it. The way to test it is to enable the firewall and then try pinging the server. You'll see that even with no rules, the ICMP packers are dropped, thus proving the firewall is enabled and works. It's in the documentation by the way : "If you enable the firewall, traffic to all hosts is blocked by default. Only exceptions is WebGUI(8006) and ssh(22) from your local network."
@@Alegzander1990 I wish it was that simple. I went down a rabbit hole and found out it never should of locked people out. And the change log doesnt show a point in which this was fixed.
Can you please help me? My firewall doesn't seems to be working anymore. Sometime ago I've got blocked outside proxmox, and I made these commands: "iptables -F" and "nft flush ruleset". Now if I enable/disable datacenter firewall, I still got access, the same happens with rules withing pve and containers/vm.
2:38 Im locked out and can´t access it anymore. I put monitor and keyboard, giving stop command but not work... Very bad idea test these, better to add before a 22 and 8006 port and then disable all others...

Thank you for the support and the views.
WTF, I never see in whole life so good explanation of firewalls... "Datacenters setting" and so on... Thank You!
Fantastic explanation of how it works, in bite size steps.

@5:41 - firewall rules order:
1. Datacenter
2. PVE
3. VM & LXC
- if i block port 80 at the datacenter, will i be able to access port 80 on a VM?
no not unless you made an allow rule for the ip address of the VM
@1:32 - why did the firewall not block you after enabling the datacenter firewall?
- does the default action to DROP is not use? or just useless?
I believe that it will not become fully active until the first rule is made.
