I just got a new Asus RT-N16 to replace my venerable E2000. I installed the latest build (tomato-K26USB-1.28.7492.2MIPSR2-Toastman-RT-VPN.trx), cleared NVRAM, assigned a static IP to my server and forwarded a port to that IP. This setting worked perfectly well for E2000 but, for some reason, the port is not forwarded in Asus RT-N16. The static IP is properly assigned to the server, I can access it inside the LAN.
I also tried assigning the IP to DMZ but the port was still not accessible from outside.
OpenVPN is not running.
Any idea what the problem could be?
