At present, because of the way the Jetstream PPP over ATM DSL setup works,
all external modems HAVE to NAT their internal networks.

You cannot get away from it; this is how the network is set up. The device
terminating the DSL connection has to NAT for downstream devices.

This is not just a Nokia issue.

The question is whether that device provides a workable H.323 proxy that
will support Netmeeting bi-directionally. (The problem is inbound)

You'll have to go to the vendors for information on that.

BTW, if you use an internal card you'll still have to NAT internal machines.
If you want local machines other than the one with the DSL connection to use
Netmeeting, then you'll still have to find a way of proxying Netmeeting.
