Thanks, I downloaded it and set it up. It is very straightforward, but I am still having trouble connecting. The Windows message is telling me that Windows is allowing the connection but a remote firewall is blocking the connection, and to make sure port 1723 is open. Could it be port 1723 on the Mac (where the VPN server is located). My Westell modem has a firewall but I logged in an all VPN connections are set up to passthrough.

How do you specifically open a port on a Mac?
