I have a question about Can't
access some websites while using a shared PPPoE connection:
Ok I got a problem that no one else seems to have encountered. If someone has and
I haven't checked thru the previous post thouroughly enough........sorry. Ok here
goes.
I have 2 computers, both running Win XP Pro. They are directly connected via a Crossover
cable, and one of them has a DSL modem attached (correctly set up). I have set up
the LAN and configured ICS to work........but it didn't.
When I tried to access the net, I couldn't get to any sites. I found this post and
tried to do the MTU fix. ANyway, i pinged the host and the higest MTU I got was 1454.
Anyway, I changed the appropriate value in the registry, restarted the computer......and
tried to access the net again. To my surprise that didn't work.
I brought the command prompt up again and pinged the host again. This time I found
that the MTU value I previously set (1454) didn't work anymore. The "new" value was
1426. I then restarted, and tried to access the internet from the client again. And
again, I couldn't. This time when I pinged the host the MTU that worked (got a reply)
was 1398.
Every time I set the MTU to the new value, when I tried again I wouldn't be able
to access the net and the MTU that I could get a response from the host with would
have dropped again. I don't know if this has any bearing on the problem, but each
new MTU value was always 28 less than the previous one. Isn't that the size of the
packet header or something?
Anyway, suffice it to say that I am extremely stumped. If there is anyone out there
that can help me, I'd appreciate it.
Thanks, Matt.
P.S. By the way, I have made sure that the host computer actually has its connection
to the net running when I try this (just in case you thought the problem was on the
hosts end).
