Current Network.


The SBS/ISA Server has 2 NICs, one internal to the local domain and one external to the Internet.

The applicable protocols/ports have been set
to allow vpn client connections:
ports = 47/1723,500,51,50,1701

Problems:

1. The VPN Client cannot connect to the VPN Server it
says it can't find the HOST name.

PS: The server has internal address starting
of : 10.0.0.XXXX
Subnet mask 255.255.255.255

I can ping the external address of the SBS/ISA Server.

Am I missing something at the other end?
 
All port 47, 50 and 51 are protocol IP ports. quoted form
Which ports need to be opened for running VPN

A: PPTP VPN uses TCP Port 1723, IP Protocol 47 (GRE); L2TP: UDP Port 1701; IPSec: Pass IP protocol 50 and 51. Note: 47 is a protocol number and not TCP port. The protocol name is GRE. It'll make a big difference when configuring your firewall or router.
