[pptp-server] Traceroute for GRE packets ??

[Martin Leonard]

There is a patch available for the traceroute program from what I remember,
that can trace GRE packets through the network.  Can't remember where to get
it but someone must know, and it should be listed on a PPTP site somewhere.

Sorry I can't help you more than that, but there is hope!
