How to make VPN work with Windows Server 2003 and a Juniper Networks firewall?
July 22, 2008 2:51 AM   Subscribe

I am trying to set up a VPN server at the office using our Juniper Networks SSG5-v92-LAN firewall/router and, if needed, a server running Windows Server 2003. The reason why I'm saying "if needed" is because the router itself seems to be able to handle VPN connections without the need of a seperate server, unless the username and password needs to be authenticated against another computer.

I'm not an expert network administrator, and after spending hours on this problem, I need help.

I tried two solutions that didn't work for me. The first one was to set up the Windows Server 2003 routing to accept PPTP VPN connections by modifying settings in the settings in "Routing And Remote Access Services." This used to work before, when the Windows Server 2003 was our DHCP. But since the DHCP is now on our router, DHCP still works fine, but even when I tell the Windows Server to relay DHCP calls to our router, it doesn't seem to do it.

I also tried to configure a L2TP VPN on the router using the built-in wizard, but that also seems to fail when I try to connect to it using a client computer outside our LAN.

Is there anyone who can help me with this? Thanks in advance!

Someone wrote in the following:
To get 2003 server to work with the VPN connection, put the IP address of the VPN in the WAN Miniport (L2TP).

Voila, you have a connections as per doing the same thing on an XP machine.
