Hello guys,

I have a Netgear WNR3500L running a TomatoUSB (Shibby mod) custom firmware, which is connected from the internet port to a Netgear DM111PV2 in PPPoA Bridging.

I'm able to get internet and everything works from the router but the problem is the whole port forwarding and NAT?

I can assign port forwards in the router but when I check them with a port checker they are still closed.
Could I get some help and info to educate me on what's going on? Is the setup wrong?

Thanks
