I'm trying to establish branch office connection to my SBS server via VPN. I've set up the server firewall to allow VPN passthrough. When I try to connect I get the error message, "xx.xx.xx.xxx is not set up to establish a connection on port 'pptp' with this computer." I get the same message when I try with the firewall down. I have a static IP address for the server and address requests to that IP address. Does anyone have any ideas? Thanks for reading this.
