(PM) NT + PM + non-routable IP block

Hello,

a. am not sure whether this problem would be better of asked to
to the NT experts of the PM experts, possibly both.

b. have a customer using non-routable IPs (Block 192.168.x) for
their LANs. They wish to have a proxy service for their users,
which will dial-in to our POP (PM2) and also be responsible for
carrying mail for their domain.

c. They are currently using MS-Back Office's MS-Proxy

d. We now give them a dynamically assigned IP, which probably they
should be given a static IP.

Question:

Is there a mechanism to route non-routeable IP LANs through
<something> in NT to routeable IP networks? I was seriously thinking
RRAS but tried it out and really funny things happened. Connections
would be setup, the gateway would get two ip's (one from our side, one
from theirs, as well as the LAN card) and then when we would ping,
from the lan to the wan, it would go out the dial-up channel AND NEVER
RETURN.

What would you recommend in this case we do? The customer lan is
geographically distributed over a large campus using FDDI and uses
DHCP, but prefers not to have real-IPs as this is a secure facility.

I would have though IP masquerading would be possible through NT4 with
SP3!
