Port forwarding to a VPN server

    Question

  • I have a server in my LAN, behind a router.
    I want to enable my users to remote access using VPN. I added the RRAS role to my server and set up the VPN.

    What ports I have to forward in my router/firewall to the server to enable my users to connect to it?

    I could not find any documents about it. I'm probably searching with the wrong terms.

    Thanks

  •     Have you checked your VPN config? Can you connect from a LAN machine to the server's LAN IP?

         What you need to do on the router depends on what type of VPN connection you have set up. If you are using PPTP you need to forward PPTP which is tcp port 1723. You also need to make sure that your router does not block GRE. Note that GRE is an IP protocol, not a port.

  • Thanks Bill, that did the trick. My router was blocking GRE.
