Hi,
Long ago I had the same problem.
You should check the XP client and it connection settings. I can't
remember the exact trick and I have no XP machine here to test it right
now, but there is some problems with multilink. You should disable
multilink on XP machine or you should enable it on both sides. The
problem is that I can't remember which of these 2 solutions worked with
me.
Best regards,
Ivailo Tanusheff

Subject: MPD/VPN
I'm open to suggestions on this one. I have tried everything :(
I'm hoping that someone else ran into this problem and knows how to fix
it.
MPD/FREEBSD as a VPN server.
Multiple clients (windows and unix).
Windows 98: Works great, connects, tiny performance drop in speed,
hardly
noticeable.
Windows 2000: Works just as well as Windows 98 if not better.
Windows XP: I can connect, ping through the VPN, even load tiny web
pages
and telnet out - but anything large stalls completely.
I've tried multiple XP machines, they all do the same thing.
It is my understanding that this is a MTU issue - but I find it very
hard
to believe that Microsoft products need configuration before they work,
such as a MTU change.
Heres mpd.conf for what it's worth (I've excluded the clients):
client_standard:
set iface disable on-demand
set iface enable proxy-arp
set iface idle 86400
set bundle disable multilink
set link yes acfcomp protocomp
set link disable pap
set link enable chap
set link keep-alive 10 60
set ipcp yes vjcomp
set ipcp dns 66.170.64.1 66.170.64.13
set bundle enable compression
set bundle enable crypt-reqd
set ccp yes mppc
set ccp yes mpp-e40
set ccp yes mpp-e128
set ccp yes mpp-stateless
One other thing - I notice that the two clients that do work
(any
Windows 98 or 2000 box) has a MTU of 1496 on the server:
ng0: flags=88d1<UP,POINTOPOINT,RUNNING,NOARP,SIMPLEX,MULTICAST> mtu 1496
The ones that don't vary but are NOT 1496.
Any input would be helpful at this point.
