Hi Guys,
I've got a Proxmox server running version 7.2 with latest updates and a pfSense VM acting as my firewall/router. On my network I have a few configured VLANs with proper rules in pfSense and everything works perfectly as it was designed.
I also have OpenVPN in my pfSense providing remote access to my internal network. And again, it works great. I can connect to my VPN and access the internal network as per my firewall rules.
The problem is that I can't access my Proxmox when connected via VPN. Any other VM in any VLAN is accessible via VPN (I opened the rule in the firewall on purpose for tests and troubleshooting). I can see from my firewall logs that pfSense is passing/allowing the traffic to Proxmox, but Proxmox on the other hand is dropping the traffic.
So, i did some searches here in the forum and on other websites, and found people saying something about the internal Proxmox firewall. Well, the firewall was disabled by default, so I was not expecting any traffic to be blocked. In fact I didn't want that firewall to be enabled because I manage all traffic from the pfSense.
Anyway, I decided to enable the internal firewall in Proxmox and apply proper rules allowing traffic from my VPN Network. And guess what... it didn't change anything.
Before you tell me there's a wiki with all information and details about configuring Proxmox firewall, including for remote access, Yes. I know, and I read everything in there.
https://pve.proxmox.com/wiki/Firewall
I even created the "management" IPSet, which is mentioned in the wiki, and it should give me the access I need.
"To simplify that task, you can instead create an IPSet called “management”, and add all remote IPs there. This creates all required firewall rules to access the GUI from remote."
Well, that didn't work either. I surely am missing something.
Would anyone know what else is required for remote access Proxmox in this case?
Appreciate any help.
