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.
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.
