    My Lenovo W520 (latest drivers for my Intel 6300) is connected to my WNDR3700v2 (latest firmware 1.0.0.32) which is connected via ethernet cable to my cable modem (Time Warner). I have assigned my laptop a static IP address and I'm trying to torrent on port x (not any of the standard ports like 80, 8080, etc.). I've set up port forwarding to open TCP/UDP for port x on my static IP address but when I test it, it's still closed. I've set up an inbound rule to accept any requests on port x (and even tried testing if the port is open with the firewall turned off). I've tried setting up my static IP in a DMZ. I can see an external (public) IP on router status. I've set NAT filtering to open and checked off respond to ping on internet port. Can anyone help me troubleshoot what options will help me open up this port?

    Perhaps your ISP is blocking the port or any ping/wan requests to it that you are using. Is your modem a 'dumb' type like a motorola, or is it one with routing functions/tables, perhaps even a silly modem/wireless router combo?

    It's not the ISP since I tested the same port on my neighbor's connection (with his permission) and it worked. My modem has a wireless router combo but I disabled everything and set it to bridge mode.

    enable upnp on the router and your torrent client and windows(if you ever disable the service) should get everything set by itself.

    You're gonna have to test something, connect your computer to your modem directly and see if you can torrent on that port. Even though you tested on your neighbour's connection you have to eliminate the chance that it's something on your computer or your modem. You should also cold restart the modem to get a new ip, assuming you don't have a static ip.

    Should all this fail, I would try factory resetting the router or better yet flashing DDWRT or tomato to your router, since the 3700v1/2 is well supported by it. Factory reset will wipe any settings you may have buggered up, ddwrt will give you iptable control if you want it (much more powerful firewalling) and complete stability. DDWRT also has the benefit of feeling like a new router without actually buying one, if you've never set it up before it will take about an hour or so to read the docs, download what you need and actually flash it.

    Ok I can get through when connected directly but when I connect to the router, I can't get through. I'm not sure why the ports are still being blocked despite setting up port forwarding...I don't want to flash DDWRT or tomato since the router is my bro's and he's away at the moment...

    edit: it seems that DDWRT even has this issue:

    Did you add a security rule for the port?
