On the other end is an OpenBSD box providing NAT services to this private network, and beyond that, an Extreme Networks switch. But this setup works fine for at least a dozen users running every type of hardware and OS you can imagine. And as I said, when I install Redhat, this same box works fine. It's just when I install Debian/AMD64 that I have these network problems, so it must be something with the software (kernel?). I just have no idea what it could be. Thanks.
Could this be the TCP window scaling problem? See http://lwn.net/Articles/92727/ Michal
