Hello everyone,

Im very new to OPNsense.

My setup is as follows: i have my ISP router and in the subnet created by it there are multiple devices including my main pc (*) and a mini PC with 2 NICs and OPNsense installed which is supposed to be the router/firewall for my homelab. For now there is only a laptop behind the OPNsense router which i use to configure the firewall.

Now to the problem: I want to access the web GUI of OPNsense from my main pc (*) but i just can not get it to work.

I tried the following things:
  • i made sure the Web GUI listens to both LAN and WAN
  • in the interfaces tab I enabled that private IPs can access the WAN interface
  • i made a firewall rule as follows:
    • Action: Pass
    • Interface: WAN
    • Direction: In
    • Protocol: TCP
    • Source: Single host or network and then my ISP subnet
    • Destination: This firewall
    • Port range: HTTPS to HTTPS

Something I noticed is that when I try to access the web GUI from my main pc and watch the firewall logs at the same time, then I see that the packets are being passed (by the rule i created)

I hope someone could help me here, I would appreciate it a lot
