hi,
i have been happily using freebsd 2.1R for about a month and recently
switched from a 28.8 modem connection to an ISDN connection using an ascend
pipeline 75 router.
i am seeing some very weird problems and i was hoping someone might have
some ideas. the router is connected to the 3c509 card in my freebsd machine
with a reversed twisted pair cable. the problem was identical when using a
cisco 753 router in hub mode with a normal twisted pair cable.
none of these problems show up when i use the ppp connection.
thanks in advance,
b3n

when pinging the router from outside i get this:
galileo> ping -s 206.145.117.1

but when pinging from outside to my freebsd machine i get:

and when pinging from my freebsd machine to the ethernet interface on the router
(or anything past the router) i get this:
black: {6} ping 206.145.117.1

this 10ms per ping decerement continues until the ping time is 10ms, at which
time it starts over again at 1000ms.
