Port Forwarding

    I'm taking the leap into bittorrent and need to set up port forwarding on my machine. Our broadband connection is a 4-port wireless router with a port that says WAN port on it that connects into the broadband modem (no wireless on the broadband modem).

    The IP of the BB router is 192.168.1.1, the wireless is 192.168.2.254. When I put them on the same subnet the wireless router wouldn't pick up the broadband router, i.e. when the wireless IP was 192.168.1.xxx it wouldn't detect it.

    When I went to set up port forwarding on BB router (standard Smart Telecom one) it told me it couldn't set it up because it was an invalid IP address (192.168.2.220, internal IP of my machine). To get around this I changed the DHCP settings on the broadband router so the netmask was 255.255.0.0, then the IP 192.168.2.220 would be in range. So it set up the port forwarding rules OK. When I try to connect to the port however it fails (I can connect to that port on localhost).

    I'm not sure whether the BB modem is seeing all the wireless IP addresses connected or if it's just seeing the IP of the wireless router. Should I just set it to forward to the wireless router instead of the IP of my machine? And then how would the wireless router know where to send those forwarded packets to? Should there be some seperate port forwarding thing on the wireless router?

    Also this is probably a subnetting problem but I can no longer access/ping the broadband modem, yet I can still route through it and access the net.

    Never mind I got it though for anyone who comes across a similar problem, the wireless modem shows a different IP to the BB modem so it can be on the same subnet and still have an internal network. You have to set up port forwarding on the wireless router and get the BB router to send all data to the wireless one.
