Our admins had blocked all outgoing ports except few like 80, 443, 110 etc. I want to use some software that utilizes other ports. So I decided to make a VPN connection to my dedicated server.

So we have:

  • Server, that has Ubuntu 10.04, external ip and I have root access to this box
  • Client, windows 7, NAT, and paranoid external firewall that blocks almost everything

How to setup VPN in this environment and configure it to use different ports like 443

You can use openvpn and configure the port you want to use it in config file.

On the client side, you use:

remote server_address_or_IP PORT

To change the port you connect on server.

If you want to change the port used by the client (local port) (not very usual but seems to be what you need), you can use:

lport PORT

directive and don't use nobind
