Indeed, thanks for the suggestion, although it does rather defeat the
purpose of having a _router_ rather than a _modem_.
If you only have one client, bridge the modem and use OSX's inbuilt
PPPoE client. You'll get a live IP and no NAT to traverse.
If you need to use more than one client you can try bridging and
then using OSX's Internet Connection Sharing to have on machine with
a live IP and the others behind a NAT.
Otherwise you can try setting the desired host as the one to be the
DMZ machine. Most firewalls have that option.

Sorry to all for coming into this halfway but it sounds like some of you are
having trouble with the type of NAT (network address translation) your
various routers/modems use. For any application needing to contact another
client behind a NAT or be contacted behind a NAT there needs to be a
mechanism to traverse that NAT. Not all NATs are the same. Some are full
cone NATs that are reasonably easy to traverse, some are restricted cone
which are somewhat harder and then there are symmetric NATs which are very
difficult and usually require some hardware on the Internet called a session
border controller. The various NAT traversal mechanisms used can cause
crashing on different routers/modems.
We are going to launch a VoIP telephone service in the next 3 months or so
and, as part of our preparation, we have tested about 20 of the most common
ADSL modems/routers. We have found similar problems with some and have had
to upgrade firmware and approach manufacturers with the problems to try to
find a solution. Some of the routers/modems even crashed our STUN server
(used for the NAT traversal) - so it is a bit of a new area for some vendors
and service providers.

Sorry there's no solution here but it gives you some idea of what may be
happening.

Subject: Re: Billion 5100 and iChat AV?
Good chance it might be like the Dlink I had. Everytime I would try
audio chat, the router would crash. I have swapped to a Netgear and
have no trouble with audio chat. Any chance you have another
router or modem to try?
Yes, my D-Link has the same problem, despite the firmware updates and
DNS changes recommended by various sources.
Have fun,
Shay
