What ports to Open for various VPN clients

[choccylad]

Hi,

I need to configure our firewall to allow customers we have on site to be allowed to connect to their companies from their VPN client.

Has anyone already configure their firewall for this. Just looking for a list of ports that different VPN clients use that I need to open for outbound traffic through our firewall.

Anyone ?

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
