@Nachtfalke:
Whe you want to connect internet from LAN to WAN then you must do the following:
Enable the CaptivePortal on interface LAN (and not the WAN interface).
The clients on the LAN network must use the pfsense DNS forwarder als DNS Server or it will NOT work.
On LAN interface you must at least allow the port 8000 which is the CP.
I enable only on LAN interface, 8000 allowed. This didn't help me.
@alltime:
One thing I might also add, we simply added our DNS server addresses to the Allowed IP list and that resolved our problem.
We were experiencing exactly what you are.
Thanks a lot! This helped me!!!! :D
Very big thanks. Problem solved.
