I have an IP address, port, username, and password for one of those VPN / proxy services that allows you to use an IP address other than what your ISP gives you, but in the 'Edit Connections > VPN' GUI I don't see where to enter a port. I enter the IP address under 'Gateway' and the username and password where it asks for it, but it doesn't work.
I try to enter it with the IP address ending with a colon, followed by the port, but that doesn't work either (e.g. "184.108.40.206:9999"). Any idea how I could make it work? I'm using Ubuntu 12.04 LTS. Thanks.
