Changing Port Numbers...

[Bob]

Hello.

What is the port used for vpn?
And is it possible to secure a vpn connection with
certificates whilst changing the port numbers?

Thanks...

Hi Bob,

PPTP uses TCP 1723 and IP PRotocol 47 (GRE). You can also use L2TP and use
certificates. It uses UDP 1701 and UDP 500.
