Reach remote side over VPN from SELF

[mzimbres]

Is it possible to reach the other side by the VPN from Self, from Firewall?

I could not make it work, looks like firewall always use the 127.0.0.1 to communicate instead of the LAN ip and network.

Tried lots of NATs and P2 combination, but, since the loopback interface is not listed to apply something…

If force the source for ping, I can reach from Firewall:

[2.3-RELEASE][root@pfSense]/root: ping -S 192.168.1.1 10.128.0.2
