Re: Proxying MS pptp through a FW?

Bruce,

#Do any of you have some good references for how to proxy Microsoft's PPTP
#through a fw from a Win98 system?

#The only reference I've been able to find on their site is for setting up
#an NT server to serve PPTP via RAS.

#I'm particularly interested in port numbers, protocols, and so forth, as
#one would need to know to set up a plug proxy, or a
#packetfilter rule.

It uses TCP port 1723 and ip protocol 47 (GRE).  You can do a search for
'pptp 47 gre' on www.google.com to get more information.  You could also
get a network sniffer like tcpdump, establish a pptp connection and sniff
the packets to see what it looks like on the network.

Regards,
Jeffery Gieser
