    Just need some info how to set up a VPN. Windows has this as options. It walks me through till I get to IP Address. What should I put as my IP Address? Is this the 192.168.2.1 which is the default gateway at work? Or do I need the IP Address of my T1 service provider? I think have it too!

    When I connect to my Belkin Router via browser, it has a secton called Virtual Services see image:

    I am not sure how to fill all of this in either.

    Computer at home:
    Windows XP
    Charter Broadband cable modem with LinkSys Router


    Computer at Work:
    Windows XP
    T1 line with a Belkin Router

    Thank You,
    Michael

    I know there are a lot of threads on this subject. I just don't know about what IP to enter and I am confused about ports and forwarding ports.

    Any help is GREATLY appreciated.

    NOt to sound stupid but How does my computer at home know where to go if I put in as the IP Address 192.168.2.1?? There could be millions of these out there??
    Do I need to put in my WAN IP in this case?

    Ok For my Router it says I needed to:
    We will list a series of lines here that will show you exactly how to forward the ports you need to forward. Vitual Network Computing requires you to forward the 5500,5800,5900 ports. Go ahead and enter the settings shown above into the Virtual servers menu.

    I did this. Still not able to access work computer?
    I followed Bob Cerelli's VPN Client and Server instructions

    The user from home enters the WAN IP address including the port Example 55.55.55.111:5500
    Is this correct?

    Ideas?

    VNC and VPN are completely different (except for the V and N).

    So for starters, since you are using VPN, you don't use ports 5500,5800, and 5900

    For information on how to set up a VPN server, see:
    http://www.onecomputerguy.com/networking/xp_vpn_server.htm

    For information on how to set up a VPN client, see:
    http://www.onecomputerguy.com/networking/xp_vpn.htm

    Might want to read those pages again.

    The IP address you put in for the port forwarding is the local LAN IP address of your VPN server. And this is on that server's router. I can't put in specifics on the web page since each computer would potentially be different.

    And typically for the VPN client, it gets the IP address from the server. Just a bit easier to configure it that way.

    :) Thank You for your reply Bob :)

    I actually went through your website to do just that:

    Here is where I get confused:
    LAN IP Address of my VPN Server: So the computer I went through the steps and set up as a server 192.168.2.3 would be the ip address?

    When I try to access from home this computer at work, What do I put as the IP Adress??
    Is this the 64.53.XX.XXX of my WAN IP? If not, and I put 192.168.2.3... how would the home computer know where the work computer is? There are probably millions of people with this address?
    :confused: :confused: :confused:
    Thank You,
    MIchael

    You put in the external WAN IP address that is used at work.

    The port forwarding it how the connection continues to your VPN server.

    OK!
    I set up work with 1723 portal forwarding
    I setup a VPN Server.

    I am now at home. I enter the WAN IP 64.53.xx.xxx
    I get an error 800
    Unable to establish VPN connection???

    Ideas?

    Error 800: Unable to establish the VPN connection. The VPN server may be un-reachable, or security parameters may not be configured properly for this connection.

    Resolutions:
    1) if you have firewall, open TCP Port 1723, IP Protocol 47 (GRE).
    I have done the 1723 port as per Bob's website. I have no idea what the Protocal 47 (GRE) is???:eek:
    2) make sure you can reach the VPN server by using ping. Sometimes, poor connection can cause this issue too.
    No Ping??
    3) You may need to updated firmware on a router or firewall if other OS (win9x/nt/me/w2
    k) works except XP.
    Firmware updated
    4) The VPN server may not be able to get IP from DHCP for the VPN client. So, you may want to re-configure VPN host networking settings. For XP pro VPN host, go to the Properties of the VPN>Network, check Specify TCP/IP address and Allow calling computer to specify its own IP address, and uncheck Assign TCP/IP addresses automatically using DHCP.
    Whew!! You lost me. The computer at work is "Windows XP home" as well as the computer at home. NO XP PRO.
    5) Make sure no other secure software blocks your access, for example, if you use Norton secure software, you may need to add the remote client's IP so that the client can access.
    No secure software
    6) If your VPN running on a Windows RRAS with NAT enabled, you may want to check the NAT settings.
    Whew! Again... What??:confused:
    7) If you can establish the VPN from the desktop at home but not from the laptop. Make sure no security software like Microsoft OneCare software that blocks the GRE.
    No Microsoft OneCare. GRE? What?

    I am very green when it comes to all this lingo!!!!:confused:
    Thanks for any input!

    And now you are seeing how complicated setting up a VPN can be.
