Heres my home network:
1 Powerbook with airport card (internal IP address: 10.0.2.2)
1 iMac with airport card, plugged into ADSL.(internal IP 10.0.2.1)

The iMac has a connection to the net via ADSL which is then shared over airport to my powerbook - (we do not have a base station, simply card-2-card).

Things like iChat Video conferencing do not work on my powerbook - they require port forwarding. So heres the thing:

How do I forward a range of ports on the imac to the powerbook using the terminal?

iChat AV uses four UDP ports in this range: 16384 to 16403.

Please help!

Sorry I don't have an answer for you, but I do have a related question that would address both our problems (if solved).

I have four Macs and a Linux box. Linux is the router/NAT, and serves addresses in the 10.10.10.x range. One iMac has an Airport card running as a Software Base Station serving a connection to a PB. This loop is in the 10.0.2.x range.

The problem: the PB isn't able to see the shared resources available elsewhere on the network (iTunes music, iChat, printer sharing, etc). These resources are shared via Rendezvous, which can't extend beyond its subnet - in this case, it's limited to 10.10.10.x.

I see two possible solutions: a) reconfigure the iMac to serve 10.10.10.x addresses via Airport, perhaps in the 10.10.10.150+ range, or b) install software that will allow Rendezvous to bridge the networks.

If at all possible, I'd prefer the first option - it seems inherently cleaner, and since it's so simple to reassign the NAT ranges within Linux, it stands to reason that a straightforward solution exists for OS X as well. Unfortunately, I haven't had much luck figuring out where this is defined. I've learned that this can be easily done with either a hardware base station or (likely) OS X Server, but neither one is available to me.

Any clever ideas out there?

I thought that Apple had designed iChat to work through routers/NAT. At least that's what's written here.
