Port Forwarding not working

rgbeard 02 Dec 2014 23:48

I have a NetGear WNR3500L V2 that I'm trying to get to forward port 22 to my Raspberry pi. It won't.

Here's some information.

I've tried reaching both 22 and 5901 from an outside connection and can't.

I thought perhaps it was only 22, at first, and that it was somehow being interfered with by settings for the admin ssh , but that doesn't seem to be the case.

I have it working by using the CLI that I received from a website. I can't post the link to the website due to restrictions on my account.

My CLI that I used was:

iptables -t nat -I PREROUTING -p tcp —dport 22 -j DNAT —to 192.168.199.96:22

iptables -I FORWARD -p tcp -d 192.168.199.96 —dport 22 -j ACCEPT

I guess the GUI doesn't properly execute one of these two commands??
