Q&A: How do I forward ports when I have a broadband modem connected to a wireless router?
orgman15 asks,
I have a broadband modem which is connected to a wireless router which I connect to with my computer. When I connect my computer directly up to the modem I have got the ports forwarded for torrents. Then when I try to hook my PC up through the wireless router the the ports aren’t open anymore. What is the setup I need in terms of ports to forward on the modem and ports to forward on the wireless router so I can use torrents. Do I need to forward the ports on the modem to the wireless router’s IP and the ports on the wireless router to my PC’s IP address, or is it some other combination?

Port forward on router(remove firewall)
http://www.portforward.com
log into your router (goto command prompt type ipconfig note the i.p address of the gateway)
type that i.p into your address bar in your web browser (you might be asked for a password its usually admin if your haven’t changed this)
from there make sure the ports for your torrent programs are forwarded properly (should be in like NAT route or port forward)
also check to make sure your firewall as well as windows firewall is configured with the appropriate port/s
the modem is what handles the internet connection so the port forwarding needs to be done there. the router passes the connection on from there.
you might want to remove the router while configuring the modem to avoid complications. once configured you should be able to set it all back up as it was
http://portforward.com/routers.htm should cover the rest
good luck mate
All you need to do is to configure it on your router, here is brief idea of port forwarding.
Broadband modem — give you external IP address (assigned from ISP)
Router — assigned all your local IP addresses to your PCs
Therefore
one external IP >>> many internal IP addresses
for example, external IP = 20.1.1.20, one of local desktop’s IP via router = 192.0.0.3, your laptop in the same network = 192.0.0.2, and your router normally = 192.0.0.1, etc.
In order for external computers to access your local PC, you need to map your local PC port into the external IP port. for example you want the outside to access your desktop via port 10345
In the port forwarding you need to set it as
192.0.0.3:10345 = 20.1.1.20:10345
(the external port number doesnt have to be same as the internal port number, you can use whatever number there).
or
if you want the outsiders to access your laptop via port 8900
the setting will be
192.0.0.2:8900 = 20.1.1.20:8900,
etc.
If you want more information about port forwarding. check WIKI, etc. you will find thousands pages talk about it.
Good luck.
