Subject: failure from bizarre NAT setup

The hotel I'm currently staying at has a bizarre NAT+gateway that's
caused me an unusual problem: ssh and telnet die with
"Can't assign requested address"
I suspect, but haven't proved, that the problem is related to messages
like this:
fetchmail: gethostby*.getanswer: asked for "machshav.com IN AAAA", got type "A"
ssh is, I think, trying to get the local address, getting some bizarre
answer, and finding itself unable to bind to it. I've bypassed the
problem by putting a BindAddress statement in my .ssh/config file, but
I shouldn't have to do that. Rebooting worked yesterday, but that
feels very Windows-like: if your system doesn't work right, reboot and
see if that helps. Ugh.
Does anyone have any clean suggestions on how to *fix* the problem?
