SSH using publickey not connecting after install 2.0

[geocash]

I have been testing to see if pfsense could be a possible solution for my environment, but ran into one issue I can not fix.

I have about 20 servers behind a pfsense 2.0 firewall. All servers have public IP on two different gateways. Prior to connecting firewall I could send communications between the servers using trusted publickey. After connecting firewall the connections fail. All other features HTTP, FTP, SSH from internet work correctly. When I look at the firewall logs it shows. "Blocked by Default Rule"

Specs;
Running in transport mode, following instructions found http://pfsense.trendchiller.com/transparent_firewall.pdf

Lan rules all all traffic/ports - I have even tried allowing all traffic/ports on wan side and it has not cured issue. Some other place I suspect that it is either truncating the commands sent or striping the computer ID.

I have set up another firewall box running the older 1.23 version and it has same effect.
