Protocol 47

[Adam Fenn <Adam . Fenn @ fennco . com>]

I am messing around with PPTP on an NT RAS server.  I thought I would
try to proxy PPTP through my bastion host.  I pulled out a sniffer to
figure out what TCP or UDP ports PPTP used.. Turns out PPTP is a
transport layer protocol of it's own, protocol 47.  Like TCP is 6 and
UDP is 17.   Anyone know how I might proxy protocol 47?  I am running a
little Linux i386 machine, with a variety of free proxy applications.

Thanks!
