I think David meant for his IP pool on the RAS server?? Am i right?

If so, I see no reason for this not to work, but it will suffer from any of
the limitations of not having a 'real ip' address. It's kinda like dialing
a RAS server in a clients office that uses NAT for Internet connectivity.

If the only purpose is to surf then should be adequate, programs requiring
real static IP (like SMTP delivery with ETRN) definitely pose some problems.
