Martin,
I am still investigating what is exact;ly happening with our pfSense-2.1.4-RELEASE(amd64).
We are in a similar situation as your setup,,other than our pfSense is staic routed to an ip phone and a teacher segment lan router that has wokred fine with pfSense-1.2.3 and pfSense-2.0.1 but with pfSense-2.1.4 i am seeing lots of traffic blocked in the fiewrall logs and i am very certain the lan and OPT inerface rules should be passing all traffic,,between lans. If I disable the static route temporarily,,this blocking stops (in the firewall logs)?
I'm not real smart but if i spend enough time on something i can usually hammer it out.
What we are suffering from is on a Windows domain dns wins smb is being blocked,,,with this scenario. Not good in a production setting.
I need to get wireshark on my setup,ro see were the packets are getting confused at.
I setup two other pfSense machines at two of our other school buildings at the same time,with a much simpler setup,,and couldnt have been any easier to setup.
Thanks
Barry
