OK, I am a little confused. Why are you running two routers? Where is your ISP in your diagram? What port(s) are you wanting to forward? Are you running a firewall? What are the IP's of the nodes on your network?

If I understand you correctly, the second router is just acting as a switch.
If so, you only need to open the port on the router connected to your ISP and forward it to the IP address of the node (a node is a device connected to your network such as a server, computer, etc) that you want to recieve the forwarded traffic.
So, lets say you are wanting to run a web server on the server that is on your network. You would port forward port 80 incoming to port 80 on the IP of your server.
Does this help?
If you are planning on allowing access to something on your network for the internet I would recommend using a fire wall that will segment your network into red, green, and orange (dmz) zones.
Smoothwall is a open source firewall that works well.

You will want a static address for the computer that you want to port forward to. Although, on your small network, your machines probably reicieve the same IP from DHCP all of the time so it might not be necessory to have a static address.
When you logon to the router to port forward, it will ask for the IP that you want to foaward to. Just enter the IP for that machine.
Can you tell me what you are trying to accomplish? (web server, ftp etc?) My ISP blocks incoming port 80 so I had to work around that to run a web server.

If you decide to run a ftp server be ready to fight hack atempts. Mine was up for 3 days and then I started getting about 3 or 4 hits a day from people trying to get in. They haven't had any luck so far but, I keep a close eye on it.
Once you set up port fowarding you will need to test it from outside of your network.
I would still recommend running a firewall that will segment your network. Do you really want the world to have access to your personal computers?

well I don't have it setup yet but I might try that firewall that you said
and do I have to still pay for a domain name?

No, a domain name would be optional. You can just use your IP address from your ISP to access your computer from the outside.
If you do decide to get a domain name you will need to know if you have a static IP from your ISP. If not, you can sign up for a dynamic DNS service (I use dnsexit.com) to adjust the dns to your changing IP address.
Let me know how it goes.
