VPN support from a LinkSYS BEFWS11 S4 v.2 Router
Posted on 2004-04-20
I can create a VPN connection within my network behind the firewall. I have a W2K Active Directory Domain employing a single internal RRAS server (also W2K). The internet gateway is the LinkSYS router mentioned above. I am trying to see if I can access my network via a VPN connection outside of my internal network. I know that the LinkSYS router is probably not designed for this but I have been able to use it's port forwarding options to gain access with pcANYWHERE and Windows Terminal Services.
From the information I have, I know that PPTP employs port 1723 via TCP and L2TP uses port 1701 over UDP. I have forwarded those port calls to my internal RRAS server so that when I call upon the public IP address of my router with a VPN session, the call should go to the RRAS server and authenticate. I also have the PPTP and IPSec pass through options enabled. However, this fails and I don't find anything in the event logs for a clue.
I am mainly doing this to finish my MCSE so this is not something I would not recommend in practice, but I would like to see if it could make it work as I have described. If the LinkSYS Router will not allow this then I would like to know now instead of wasting any more time.
Thanks for any replys.
