PfSense stops resolving DNS

[renepc]

Hy all

i have 2 pfsense firewalls with following configuration:

WAN: PPTP Tunnel with fixed IP Address
LAN: 192.168.x.x/24 Network

NAT

since i've put the PPTP-Connection into WAN-Setup, the boxes stopped resolving DNS.
i can use the same Namesevers as i put into System->General Setup behind the walls (fixed entry in the windows client) and i can resolve DNS.

if i set WAN to static IP Address the walls can resolve again.

do u know this problem? can u help me?

Did you set any DNS servers on the pfSense?
Are you allowing the manual entries to be overridden by DHCP on WAN?
