I have a multi wan setup with 3 WAN interfaces and 1 LAN. It is using policy based routing. DNS refuses to work. This is because the pfsense machine can not resolve anything. The DNS servers are correct. They are pingable from the pfsense machine. They are accessible from machines on the

I've always had problems with MS DNS implementations. They have messed around with DNS and so it exhibits strange behaviour. I'd suggest that you get rid of the MS machines IP as a DNS server on the firewall. On your XP PCs have the firewall as the primary DNS, and the MS machine as secondary.
