Do you mean on your server or your own computer?

You can do a telnet test or get a program that checks the ports that are open.

Easiest way is to try and telnet to a pptp vpn and see if the connection is allowed to make it as far as the vpn server.

If you are doing vpn in particular make sure your router is also not blocking it and has a vpn pass through mode. Generally it is enabled by default but not always.

That is for inbound port checking, not outbound. That will just see if your ISP blocks it going into your computer, not out.
