I'm having trouble establishing a VPN tunnel into my home network.

I have a Terayon TJ715x cable modem, connected to a Linksys WRVS4400N wireless router with VPN.  I spent an hour on the phone with Linksys tech support today and the tech thought that my cable moden needed to be switched from "router" mode to "bridge" mode because the status tab of the routers web tool shows the internet IP address as 192.168.x.x when it should be the outside IP of 72.231.x.x  (this is the IP that shows as my external IP when running an IP test) After some searching I was able to log onto the cable modem but I cannot find any way to make this configuration change or even if its even possible wtih this particular cable modem.  I'm running Vista on my IBM T60p laptop that holds the shared folder that the VPN tunnel will connect to.  The PC that I'm having difficulty establishing a VPN into my network is running XP Pro with the latest VPN client availalbe from Linksys's website.   Note also that the Linksys tech tried to connect via VPN with the Linksys VPN client and couldt not establish a connection either. Any help would be greatly appreciated.

I finally figured this one out for those of you that are interested.   I had installed a VOIP router (Vonage) between my cable modem and my Linksys WRVS4400N which was causing the problem.  The Linksys VPN router thought the external IP address was the IP of the VOIP router (status tab on the router web page showed external IP of 192.168.x.x).   Turned out to be simple cabling issue.  I re-cabled so the cable modem connected first to the VPN router, then off one of the switch ports to the VOIP router.  Now the VPN router sees the correct external IP address: 72.x.x.x and the VOIP works fine.   Did require a boot in sequence to get it all working propertly though, first the cable modem, then once up and running the VPN router, then once up and running the VOIP router.
