NAT for dial-up pools...

begining to think that a great idea for IP conservation won't work in
the application we need it to:

providing dialup access using as5300, IOS 12.1T...

Currently have the NAS providing non-routable IP addresses from a pool
(no problem) and using NAT to have them all access from a single IP
address. Authentication, connection, the whole shebang works
flawlessly.

However, out test base is reporting that services such as ICQ,
Netmeeting, and other applications that want to establish point to
point communication cannot do so. Assuming that ths is a result of
the NAT being unable to establish the connection on behalf of the
port. Should not they be able to establish from thier location outward
to the other user, or is this more limiting than initially suspected?

Given the widespread use of these applications, is the best
recommended course of action to allocate one ofthe IP address blocks
to the dialup pool, and just give them all valid IP addresses?

Comments, recommendations?

Thanks

Dave
