Hello list.

I have machines in my DMZ that are available from the internet (IMAPS 
etc.). To make the machines available to machines on the LAN, I have had 
to override the IPs of the public machines using the DNS server on mono.

This work s fine for machines on the LAN.

When machines connect to the PPTP VPN from the Internet, they are 
assigned the DNS server on mono. This changes the IPs of the publically 
  available machines. This makes the VPN users loose the connection to 
services.

So what I want to do is:
Make the machines on the VPN PPTP use a DNS server that does not change 
the IPs of the public machines.

My clients are on OS X 10.5. I can specify a DNS-server for the 
VPN-connection, but it ends up having lower priority than the 
DNS-servers assigned by mono.


Thanks,
Tobias
