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. If you are interested, check out the terrific article in the IP Journal by Geoff Huston at http://www.cisco.com/en/US/about/ac123/ac147/archived_issues/ipj_7-3/index.h tml Sorry there's no solution here but it gives you some idea of what may be happening.
