Ports Needed for VPN Passthrough

I have had a note on my desk listing the ports needed for Virtual Private Networking (VPN) to work. I’ve used the VPN ports for opening up our firewall and for setting up our QOS (Quality of Service).

Here is the list of VPN Ports from my desk:

Ports Needed for PPTP VPN

- TCP Port 1723
- UDP Port 500

Ports Needed for L2TP VPN

- TCP Port 1701
- UDP Port 500

Ports Needed for IPSec/ESP

- UDP Port 500

It’s proven to be a pretty useful list for me while setting up Virtual Private Networking, so hopefully it will be helpful for you as well…
