as you know pptp port is 1723 by default,know I forward port number 21 to 1723 on my CentOs VPN.
Know I wanna connect to my vpn (pptp) from port number 21.
How can I do it?
You can change this within your client config: The line looks like remote 192.168.100.1
You can add the port after the ip address:
remote 192.168.100.1 21
