Trying to set up a VPN behind at Linksys WRT54GS router, have the accounts made, port 1723 has been opened and forwarded to the local static IP of the server (my machine) and no success. My friend is getting error 800 when he tries to connect. I have SBC DSL with a dynamic IP (which he can ping) but it won't let him connect. VPN settings are all set to allow in router setup, and router has been updated to firmware v 4.70.6. Under the connection properties in Windows XP Pro, I have allowed caller to specify IP address and opened the range from 18.104.22.168 to 255.255.255.255. I even turned off the "block anonymous internet requests" checkbox in the router setup. Any suggestions would be appreciated. I can connect fine with my other machine (on the same LAN) but when he tries to connect over the internet is when we have a problem.
