In order to get multi-wan working behind squid, I'm using two PCs each with pfsense. The one acts as the multi-wan/snort/firewall/pfblocker and the other as the squid/squidguard/mailscanner.

However, I can't get the NAT figured out. I have some servers that needs to be routed through specific gateways. Obviously, once they pass through the NAT of the pfsense/squid, the pfsense/multi-wan doesn't know where it came from. So I need to disable NAT on the pfsense/squid, but can't get my head around it.

I have:

Network (192.168.0.0/24) –-> (192.168.0.1)Pfsense/Squid (192.168.10.2) ---> (192.168.10.1)Pfsense/Multiwan  ----> WanPPPoE/OPT1PPPoE/OPT2(static)

Say for instance I want to route dest port 25 from 192.168.0.99 always via OPT2 - how would I do that?

I tried going to NAT Outbound and disable NAT but I get unexpected result.

Please help.
