no port forwarding

[GoogleCodeExporter]

No matter what port i want to forward its just not working
Port is not forwarded to the internet no matter what settings i make.

RT-N56U_3.4.3.9-095_dlna / Windows7 64Bit

I wanted to forward ports with the router from a localIP to the internet but 
its just not working.
Port Range is 12000 and i entered it under Port Forwarding / Manual Port 
forwarding. LocalIP i choosed from the list so should be fine, LocalPort (what 
do i need to enter there?) i let it blank and Protocol is TCP.
Working fine with the ASUS firmware but there is no field for LocalPort.
Am i doing anything wrong or why i cant forward any port to the internet?

I also tried DMZ with the Local IP which should open all ports to the device 
but also this does not work at all. Ports are still closed.

Help would be greatly appreciated. Thank you.

Port Forwarding works perfectly. On all builds.

May be your ISP offers private IP addresses on WAN (router behind NAT)?

With the ASUS firmware it is working perfectly.

So either i am doing something wrong or it is not working on my router with 
this firmware. Like i said...also DMZ is not working and should open all ports 
to the device.

Changed firmware back to the ASUS and all is working fine again...i just really 
wanted to use this custom firmware...
