DNS Proxy Problem

[dino]

Hello everybody,
first my config:
i have a standard PC hardware with 3 NICs, LAN, WAN and OPT1
WAN traffic goes to an DSL-Router, OPT1 traffic to a VPN Gateway, policy based via firewall rules
I configured a DNS Forwarder to resolve hostnames from the VPN net.
So far it works perfect.
But when i activate the squid proxy, only hosts fron the LAN and WAN interface are resolved.
To reach hosts on the VPN over OPT1, i have to enter the IP, cause DNS doesn't work.

I think that when i activate the Proxy, the DNS forwarder is ignored.

Any ideas to fix my problem?

thx. Dino

solved, it wasn't a DNS problem, but a problem with my routes
