Trouble with a LinkSys BEFVP41/SSH Sentinel VPN

I am trying to setup a VPN between an office network and a dialup computer and I am having no luck initiating the VPN. The error message I receive when trying to connect to the vpn server is: “Cannot open the VPN connection. Check that the gateway is online and verify that you are using the correct authentication key.”

On the Server side I am using a LinkSys BEFVP41 (firmware 1.40.3, Apr 24 2002) behind an Actiontec DSL Gateway. On the host side I am using the SSH Sentinel client (v1.4 build 177) running on an XP machine.

I have read and followed SSH’s guide “VPN Connection to Linksys BEFVP41” and other than modifying some ip settings to fit my configuration I have followed that document.

The configuration of the ActionTec DSL modem is:
==>WAN:
IP Address: 63.230.92.24
Subnet Mask: 255.255.255.0
Gateway: 63.230.92.24
DNS: 207.108.240.1 and 204.147.80.5
==>LAN:
IP Address: 192.168.0.1
DHCP Server On
==>Port Forwarding
47 tcp 192.168.0.100
500 tcp 192.168.0.100
1723 tcp 192.168.0.100
50 tcp 192.168.0.100
==>VPN Pass Through
Enabled

The configuration of the BEFVP41 is:
==>LAN:
IP Address: 192.168.0.100
Subnet Mask: 255.255.255.0
DHCP server: Disabled
==>WAN:
IP Address: 192.168.0.10
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.0.1
DNS: 207.108.240.1 and 204.147.80.5 and 0.0.0.0

I’ve got the tunnel from the host defined to connect to the wan ip address of the ActionTec. I’ve matched up the key and security policies. When I try to connect I get the above message. I’ve checked logs and it seems that the host never even tries to connect to the vpn router.

One curious thing…don’t know if it is related: a PC sitting inside the BEFVP41 can ping both the LAN and WAN ips of the BEFVP41 and also ping outside domains like yahoo.com but that PC cannot ping the LAN ip of the ActionTec. Do I have a routing problem?

I’m at a loss, please give me some things to try. Any suggestions will be appreciated.
