Static route bug??

ph0505

I have two sites connected by a IP VPN. Installed pfsense 1.2.3 and 2.0 beta 3 is the same problem.

Site A
172.16.0.0/16

pfsense firewall
Internet gateway IP 10.1.1.1
LAN IP 172.16.1.253

pfsense setting for static route
172.20.0.0/16 gateway 172.16.1.254
firewall rule no setting

Site A to Site B gateway 172.16.1.254

Site B
172.20.0.0/16
Remote Desktop server 172.20.1.1

Site A, The computer's default gateway setting 172.29.1.253
1. Ping 172.20.1.1 is normal
2. Using remote desktop connection is broken. Than what they resume back online. This problem has been recurring.

Site A, The computer's default gateway setting 172.29.1.254

You have asymmetric routing somewhere causing issues with stateful filtering. Where that is isn't clear from your description. Try the bypass firewall rules for local networks/static routes under System>Advanced.
