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…

It’s hard to remember all the ports! I’ve made this list a favourite!

According to Wikipedia, PPTP uses both TCP and UDP… I’m not sure if L2TP does the same.
Here’s my ACL to allow VPN traffic (somewhat relaxed):
permit tcp any 10.6.14.0 0.0.0.255 gt 1023 established
permit tcp 10.6.14.0 0.0.0.255 any eq 1701
permit udp any any eq 1701
permit tcp 10.6.14.0 0.0.0.255 any eq 1723
permit udp any any eq 1723
permit udp any any eq 500
It is assumed that internal network is 10.6.14.0/24.

[...] enable port forwarding on your router depending on the protocol you used (default is PPTP), over these ports. Then create a new outgoing VPN connection on their PC that points to your IP address, and voila. [...]
