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

Thank you, but it didnt change anything
Check document (https://docs.opnsense.org/manual/firewall.html#policy-based-routing).
Editing the rule, at the bottom, you'll find "Advanced features".
Click to "Show" them and change "reply-to" to "disable".
Regards!
