22.1 Legacy Series / What firewall rule blocks my traffic

« on: June 08, 2022, 02:32:36 pm »

Hi there,

I have a strange issue to troubleshoot.
I have setup that looks like this:

Provider-Router (wan: x.x.x.x, lan: 192.168.111.1/24) -> Opnsense (wan: 192.168.111.2/24, lan: 192.168.112.0/24)

I know this setup is not ideal but it is something i have to deal with for now.
Some of my clients are connected on the provider-router's wifi and receive a dhcp ip from the 111.0/24 subnet.
I want these clients to be able to connect to the opnsense management interface on the WAN address.

To make this possible i;
- Disabled the block bogon networks setting
- Disabled the block private networks setting
- Created an allow rule on the WAN interface that allows 80/443

I am however still unable to access the management interface.

I was hoping that i was able to monitor whats beeing blocked by navigating to:
Firewall > Log files > Live view

But for whatever reason i dont see the traffic beeing blocked there.

I know for a fact that something on opnsense is blocking my traffic since a "pfctl -d" through the command line magically makes things work as expected.

Can anyone point me in the right direction how i can monitor what's actually dropping my request?

Thanks!
