Re: Open a port for a VPN Router

For pptp -- TCP 1723 and protocol 47 [sometimes referred to as pptp
passthrough].

For lt2p -- UDP ports 500, 1701. Protocol 50 [ESP, sometimes referred
to as ipsec passthrough].
If using Nat-t, UDP port 4500 needs to be open also. --- Steve

Hi Group. I have a Windows 2000 server that I will enable as a VPN server.
This server is behind a firewall. What port do I need to open in order to
enable this? Is it a different port if the server is a 2003.

If I didn't provide enough information, please let me know. Thanks in
advance and, have a great day,

Gabriel Henao.
