VPN tunnel not working with Linksys BEFSR41

[Spuddish]

I have been trying to set up a VPN connection to my house. I am using the built in WindowsXP Pro VPN connection. The home computer is behind a Linksys BEFSR41, with the Linksys port fowarding to the home computer:
1723->1723
47->47
500->500
50->50
The VPN connection works within the LAN as it should, but when I try from outside the LAN it never gets past the "Verifying User Name and Password" screen. I've tried it with encryption and without, and it never works. PPTP passthrough is enabled, everything is updated. What in the world am I doing wrong? Everything appears to be set according to all thw articles I've read.

Good news is that your router config is OK, the client is getting through to the server. Sounds like your doing PPTP, in which case you can eliminate the forwarding of all the ports except 1723. Leave PPTP passthrough on. Shouldn't make it work or not, but you don't need the others.

If you wait long enough, you should get an error message on the client side, may take several minutes. May or may not help determine what is going on.

I would suspect a problem with IP address assignment to the VPN connection on the server side. Pulling addresses from DHCP often doesn't work well. Try assigning a block of IPs to the connection. The IPs should have the same RFC specified network address as the network there. You will also need to exlude that block from the DHCP server on the router.

Also, the network address on the server side must be different that the client side, so if you are using 192.168.1.xxx on the server side, you would want to assign your VPN connection 192.168.1.(200-254) and the client side could use 192.168.2.xxx. Which numbers are on which side doesn't matter, and you can use different ones altogether so long as they are different.

I did what you said and I still get error 628(connection terminated by VPN server), and I've double checked the security settings again and again. Just to test something, I tried using Remote Desktop (fowarding port 3389) and it works perfectly. I'm baffled to say the least.

I see this problem all over this forum. Has anybody fixed this yet. I have used the DMZ with success, but only in firmware 1.37. I have a new router with 1.4x and it won't work no matter what I do.
