> It looks fine, the call is established and PPP/GRE packets go in both
directions.
> Please also attach a ppp log from both sides with the "debug" option enabled.
The PPP/GRE packets going in both directions are "PPP LC Configuration Request
and PPP LC Configuration Reject packets" alternately. I've attached the PPP
log from the Poptop server (after enabling debug in pptpd.conf). I've also
attached a tcpdump of a successful connection (without ip_nat_pptp loaded) and
the corresponding PPP log. The Windows XP clients do not have any useful
logging that I am aware of. The error message they display is "Disconnected.
Error 619. A connection to the remote computer could not be established so the
port was closed." Since I applied the new patches I have found that loading
then unloading the ip_nat_pptp module freezes the server and it has to be hard
reset. Prior to applying the patches I could load and unload it multiple times
without problems.
