    Hi folks,

    I have a problem with the default VPN Connection from 2000/XP

    I tried to use the default VPN Connection from 2000 and XP but it doesn´t work. (Server not reachable or down)

    I called the local linksys support team and they told me to configure my network connection to VPN-PPTP but it still won´t work!

    Then i tried the linksys QuickVPN and there was no problem at all!

    Does anyone know how to configure the default VPN connection or maybe a site where i can get the needed infos?

    Firmware is 2.37(US Version also tried the EU Version)

    thanks in advance

    The WRV54G doesn't support PPTP only suports IP Sec.

    Any reason why you need to use the built in Windows VPN client?

    Where did you get the info that WRV54G doesn't support PPTP?

    In the security VPN page of the router setup there is an option to allow or not different VPN protocols, and one of them is PPTP.

    I am trying to get my new WRV54G router to work with the VPN of my Win2K server RAS/VPN. If I DMZ to the server, remote VPN connections are possible to the server, but if I only port forward 1723 then no connection is possible. Apparently more ports are needed to be open but which? I have tried forwarding all the relevant ports to VPN to no avail, only when I DMZ, a thing I definitely do not want to have, will Windows 2000 VPN work.

    What is curious is that my old linksys router worked fine with just 1723 port open.

    Eventually I plan to take off the VPN functionality of the Win2K server and use only the VPN of the router. But in the meantime I want to get this working in case I have to go back.

    I am using firmware 2.37 for the router.

    If you want to setup a PPTP server behind a WRV54G you need to not only port foward 1723 (PPTP) but also the GRE protocol (protocol #47). The Web interface only allows you to port forward TCP or UDP (not GRE).

    So complete the following:
    [taken from http://www.tek-tips.com/viewthread.cfm?qid=808373]

    From the web interface, create a forwarding rule called GRE for port 47 using the TCP protocol. (Don't worry, we'll be changing this once inside the router)

    In the config file look for this:


    (-########## will be a service number) Replace (17) or (6) with (47).

    Import the new config.

    Note: If you make any changes to your config it will rewrite the protocol section of your config so you will need to redo the above.

    Yes and after the word PPTP is says Passthrough :roll: You can run a PPTP VPN server from behind a WRV54G but you can't get it to act as a PPTP VPN server, which is what I think the original poster wanted to do.

    Thanks statiic, that was exactly what I needed :)

    I wonder though, wouldn't it be better if the protocol 47 be specified in the PPTP forwarding?
