<![CDATA[Route Traffic through two IPSEC tunnels (NAT)]]>I'm trying to route traffic from site A to B to C/D/E/F...

Site A and B have pfSenses running. Sites C/D/E/F have different firewalls in use.
Between site A and B I have a IPSEC tunnel.
Site B to C/D/E/F are existing IPSEC tunnels that only allow subnets of site B to connect and cannot be changed. The subnet of site A is not allowed to connect directly to C/D/E/F. That's why I'm looking, how I could route the traffic from site A heading towards C/D/E/F and back.

I also tried to NAT the traffic from site A on the pfSense to a small IP range of subnet B to get it accepted in the second tunnel to C/D/E/F. That seemed somehow to work, but the traffic didn't find it's way back through the tunnel B to A.

Does anybody know, how to configure it on the two pfSense?

Cheers
Chris
