Hi.
You have to create a phase by network you want to give access to the tunnel. For example, I've to create tunnel between these 2 offices:
Main office:
DATA VLAN: 192.168.1.0/24
VOICE VLAN: 192.168.2.0/24
LAB VLAN: 192.168.3.0/24
Remote Office:
REMOTE LAN: 192.168.100.0/24
I want ot give access to DATA VLAN & VOICE VLAN only. So I've to create tunnel (on both pfSense) for these trafics:
DATA VLAN & REMOTE LAN (192.168.1.0 & 192.168.100.0)
VOICE VLAN & REMOTE LAN (192.168.2.0 & 192.168.100.0)
With the pfSense v1.3, you can do this with adding several phase 2 for the same phase 1. I don't know how you can do this with older version.
Hope this helps.
[EDIT] I've added a screenshot of my configuration.
