Hey guys! I work for a WISP that has one static public IP address and we’ve natted our balance 580 over to our own static IP address scheme within our network. We have several clients using a number of VPN connections to
work from home and there is no problem. A new client of ours is trying to use a microsoft VPN connection and its saying something about a GRE connection. I found how to access the GRE tunneling feature, but now Im not sure as to what goes where in the setup. It first requires you to setup a new GRE profile. You first apply a name. Then a box is checked for “active.” Then you have three boxes to fill. Remote GRE IP address, Tunnel Local IP address, Tunnel Remote IP address. Then I can choose which WAN connection its on, and finally theres a section for Remote Networks with a box and a subnet mask dropdown menu, which in this section I can add or remove that last portion if its needed or not.
Ive dealt with port forwarding issues before and I dont feel like this is that kind of issue, but I was wondering if anyone had some thoughts on what goes where and what each means. Thank you!
