Can't access WebGUI from WAN - Solved
I am having issues accessing the WebGUI through the PPPoE interface on HTTPS port 443.
My PfSense release is 2.1
I have a firewall rule to allow my source address to access the WAN address on TCP port 443.
I can access the console on port 22 from LAN and PPPoE interfaces.
I can access the WebGUI only from the LAN interface.
If I run a "tcpdump -i pppoe0 -nnvv port 443" command I can see the traffic reaching the firewall.
If I run a "pfctl -vss" command I can see the connection in an "ESTABLISHED:ESTABLISHED" state.
I have tried firefox and IE but WebGUI is not presented to me from the internet.
Anything else I can check?
For any others experiencing this issue, I managed to resolved the problem by reducing the PPPoE MTU from 1492 to 1452
