Hi there,

Does anyone know if it is possible to set up a PPTP tunnel through the AltaVista 98 Firewall? I am able to set up a generic proxy for port 1723, but I am unable to find a way of allowing protocol 47 through the firewall.

Any ideas?
Regards,

Gary.

I assume You are using Unix.

Edit /etc/protocols and add a line like:
gre 47 GRE # Generic Routing Encapsulation

Configure the GXD for tcp port 1723 with the appropriate security

edit /etc/screend.conf and add something like:

between interface red and host "ip address og the pptp system" proto gre accept log;

or
between host "external ip" and host "internal ip" proto gre accept log;

Hope it helps.

Bye Bruno
