Hi, I am trying to create VPN access for mobile users
using existing hard so what I have, are a Firewall
(hardware) and a win2k app server acting as RRAS - VPN
server. A nic of this server has a static IP (nat on
firewall).

All conections are ok, in fact this ip is used to access
from internet to a specific tcp application port without
problem.

The problem I have is to permit the tcp-udp ports needed
for the conection with the MS VPN server. I 've been
reading about it in technet, but I must be committing a
mistake cause i can not get the server!.

I `´ve been open tcp por 1723 for pptp conection and when
I try from VPN client (xp) seems to conect but stop
responding while validating user and password.

What i dong wrong?

thanks
 
Besides TCP 1723 you also need to allow IP Protocol 47 (GRE).
