Hi,

Bought the c5400 router last week. Very fast router, 17 devices connected and no problems.

But... When I try to connect with my home server the router don't let me through.

Specs:

Windows server 2016

Installed RAS (Remote Access) using VPN L2TP / IPSec

Windows 10 client use the build in Windows VPN connection

Internal connection is no problem. Connection from out side is also not a problem when I use DMZ mode but that is not the way to do. 

So what is blocking the connection? Some Ports?

I have forward the following ports:

I have bound DDNS to my ISP IP Address

L2TP is enabled.

Kind regards,

Dante
