Hi all

I have a windows 2003 ppt l2tp server. I configured this via the routing and
remote access on the 2003 server. My question is if the server only ahs one
network card in it can it be setup to accept inbound pptp or l2tp VPN
connections? if so my what ports do i need to open up on my sonicwall tz170
firewall, and is there anything special i need to do to the internal RRAS
server to get this to work?

Thansk a ton I know this is probably more of a firewall question but the
documenttaion on this on the sonicwall site is less then informative, so im
trying my luck here

Thanks again
 
you can have just one NIC to setup VPN. quoted from
How to setup VPN on w2k server with one NIC

Symptoms: When attempting to create VPN on w2k server with one NIC, you may
receive "You have chosen the last available connection as the Internet
connection. A VPN server required that one connection be used as the private
network connection" if you select the NIC.

1. You should highlight No internet connection instead of the NIC or LAN
connection.
2. You may try "Manually configured server option".

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: UDP Port 500, 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.
