Tunnelblick

tunnelblick is an application for your Mac that allows you to configure
and manage VPN sessions. You can use this e.g. if you are connecting to
tilde.club via a network that does not allow high UDP ports; with a
properly configured tunnel, you can still run [[mosh]] as your shell and
keep on truckin.

To find a VPN endpoint, see the VPN Gate[2] project.
