Thanks again, Moak.

A suggestion that just occurred to me is this. Perhaps in your session initiation protocol each peer could communicate to the other whether it's using a dynamic IP address to connect to the Internet. That way, when the connection is lost, the remaining peer could stop trying, since it's likely that the original peer will have a different IP address next time.

Again, it seems like this is a protocol designed for static IP addresses. I hope it doesn't expect domain names to remain static as well! In the modern world, where universal ad-hoc connectivity is becoming the norm, perhaps some changes should be made.

By the way, I was getting a _lot_ of connect attempts, not just a few. There were also many attempts to connect to port 137 (NETBIOS?).

Thanks for all the help
