Can't access Web UI from OPT2

[thej0nix]

Hello Community,

I'm currently trying to setup my own OPNsense Router with the Version 22.7.9.
The setup is running on top of Proxmox. There are two network NIC's forwarded by PCI passthough into the Proxmox VM (WAN for later and the future LAN network) and two bridges - one for the other VMS running on the Proxmox (OPT1) and a temporary bridge (default Proxmox bridge) (OPT2) used to get currently access to the WEB UI and Proxmox from another network for setup.

All interfaces currently listen for WEB UI. But I can't get access to it - only when I run 'pfctl -d' to disable the firewall. The logging says that is blocking the access:
   OPT2      2022-12-17T20:01:26   192.168.0.112:56826   192.168.0.113:80   tcp   Default deny / state violation rule

... so I tried to allow in all interfaces all traffic - also completely open. It works for all other stuff, except the WEB UI - it is always blocked. I have no idea why.

Or is the problem the gateway, which is defined in the rules?

This may have nothing to do with your problem, but because I've just spent hours trying to figure out how I locked myself out. Check out my post from before:

Default rule is from LAN and not OPT2.

You need to create a rule to LAN address and make the FW listen to OPT2 interface.
