Has anyone setup a VPN on windows 2000 server? We also have a CISCO 1721 router for our T1. I was able to create and setup a VPN on 2000 server, but unable to connect from outside world. I also haave a Sonicwall firewall between the cisco router and the servers

Have you opened the ports? quoted from http://www25.brinkster.com/ChicagoTech How to open Cisco PIX 515 firewall ports for inside VPN accessing outside VPN server Symptom: When attempting to connect to a VPN server on the outside of the PIX it returns error 721, the computer failed to respond. Resolution: In order to PPTP through a PIX, you must have a one-to-one mapping from the external IP to an internal IP for type 47 GRE packets and port 1723. Add for pptp: conduit permit gre host x.x.x.197 any AND conduit permit tcp host x.x.x.197 eq 1723. For l2tp over ipsec: conduit permit esp host x.x.x.197 any, conduit permit udp host x.x.x.197 eq 1701 any AND conduit permit udp host x.x.x.197 eq 500 any.

we have a site to site VPN running using the sonic walls but client to site is not working using win 2000 server to any client

Do i have to set up an ACL? cant i just forward the incoming requests to the address of the VPN server?
