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.
Question, I am trying to give an employee working access to our network from her home office. Is a VPN the solution for me. And if so, where do I start.
Thanks for your help.
Hi, thank you for the list of ports. May I ask which windows’ services need to be enabled to be able to use VPN? You see, I have some services disabled for performance reasons. Any adviced would greatly be appriciated. Thanks.
Dear PAT,
Remote-Access Vpn is the right solution for you.
You may buy a Cisco ASA or a router for that.
I work for a cisco partner and could certainly help you out in purchasing. visit the url to know more.
