@craggy:
I've tried everything I can think of but no way can I get this to work.
no matter what I do I cant get a second phase 2 to come up when it uses a subnet that doesn't directly exist on a wan or lan interface.
is this a bug in pfsense 2.1 or am I doing something stupid?
please can someone help, I really need to get this working.
Another way to do this would be to use a larger subnet on the first Phase 1 of the WAN.
I.E.
You have 3 networks:
192.168.100.0/24 A
192.168.101.0/24 B
192.168.102.0/24 C
So when you setup the phase 2 for A to B, on the B side you set the remote WAN to 192.168.0.0/16
