[Help] How to Port Forward a Retro [Help]

[usernamehere]

Hey,

I know that if you are port forwarding you go to your ip gateway and put ports etc..
but i have 2 routers; 1 that really gives internet access to our computer, and the other which we bought to connect
it with the other one so we'll have wifi, and yes my laptop is using the wifi..

In the first router it's gate way is 192.168.1.1
And i don't know if this is where i would port forward cause it has
Port Forward
screenie:

You must be registered for see links

ip/port filtering
screenie:

You must be registered for see links

I don't know which i would go.. but i fill-upped Port Forwarding and when I go to my ip.. it goes to my gateway.
screenie:

You must be registered for see links

and here is the other router.. i port forwarded..
screenie:

You must be registered for see links

and when i got to my lan ip address it goes to localhost.. so that is already port forwarded..
screenie:

You must be registered for see links

And then i got a domain in dot.tk and had a dns service in freedns.afraid.org and it worked when i got to my domain it goes to my hotel... BUT.. only I can access it.. when i told me friend to go there she can't open it..
