Port to VPN

In my network, I have a router (linux) on internet link, and my VPN Server
behind this. What's ports I need to open in linux to give VPN access?

quoted from http://www.ChicagoTech.net
Which ports need to be opened for running VPN

A: PPTP VPN uses TCP Port 1723, IP Protocol 47 (GRE); L2TP: UDP Port 1701;
IPSec: Pass IP protocol 50 and 51. Note: 47 is a protocol number and not
TCP port. The protocol name is GRE. It'll make a big difference when
configuring your firewall or router.
