Site to site PKI VPN client connection trouble

[tcristino]

I've built a Site to site PKI with open VPN setup, all the routing between client (branch office) and server on main office are working great, but the cliente only connects to server if i issue a pfctl -d, waits for VPN connection be stablished and after that enable the firewall again (pfctl -e).
I created a WAN rule for 1194, but without sucess. I can't figure out what's causing this issue…
