I have another problem. I'm trying to talk to a host (MontaVista Linux
based router/AP) that is on the same network segment. If rfc1323 is
on, I can't browse the router's webpage: after a few bytes transfered,
I only seep TCP keep alive packets. But a telnet connection works well.

If I disable rfc1323, everything works as expected.

Maybe this is related to PAWS, but I don't the router at hand.

If you need a tcpdump, I can only give it to you during the upcoming
week.
