Hmm, I can smell that you are fired up, egged on by configuring your Modems. And so, FOTW,  I present to you, a guide on configuring your Torrent client. All Torrent clients have a window from which you can change various options. Open it by pointing your mouse to Options – Preferences. Or in most cases, press Ctrl – P. The most important options that we shall talk about are: Connection, Bandwith, Bittorrent, and Scheduling. Its a lot to read, but all points are important.

• Connection: You have to enable UPnP Port Mapping, NAT-PMP Port Mapping, and add to the windows firewall exception. Also you have to add an exception to your antivirus/firewall. The notable point here, is that the port number should be the same as you used while updating your iptables. Confused? Read this and this.

• Bandwith: This tab concerns with managing your bandwidth (speed, as many people call it). The maximum upload rate decides the upload rate of the client. If its the upload rate of individual torrents you want to change, right-click on the active torrent and do so from the properties. Same goes for the Maximum download rate. Global maximum number of connections mean the overall number of connections the client makes with other peers (connected computers). And maximum number of peers per torrent is also the same, except that its on a per torrent basis.
  eg. Global peers is 150, max peers is 100, and you have 2 torrents active. So the client will try to connect to 200 peers (2 x 100) but will be limited by global limit of 150.
  Remember that connecting to peers consumes significant amount of bandwidth. So, make sure that the global maximum number of connections and connection per torrent is proportional to the swarm of uploaders and downloaders.
  For a 2Mbps line, Global limit of 500 and per torrent limit of 200, with 3 torrents active is sufficient to give good speed.

• Bittorrent: This are basic features, It wont hurt if you enable all options like DHT, Local Peer Discovery, Scrape Information. But ensure that Protocol Encryption is enabled. Thats because, ISPs world-wide are aware of torrent data passing throught their networks, and hence everything they can to throttle it.

• Scheduler: Tired of waking up at odd times to avail free bandwidth? Can’t be at two places at once? Use the scheduler to automatically do it for you. If you followed all my instructions, all you need to do is set-up your scheduler according to your time schedules!
  
  Here, the green color means the client is active, it will download as well as upload without restriction on speed (i.e.  whatever is specified in the Bandwidth Tab). The light-green color says that upload will proceed according to the speed-limits (specified on the same page below the table, not in above picture).
  The above snap is from my client, and heres how it is organised. There are 24 horizontal boxes, one each for every hour of the day,starting from 0000 Hrs. Making that box (that hour) of your desired color, will cause the client to follow the mentioned action. So the above table means: My client is active from 2 AM to 8 AM, since boxes number 3 to 8 are greened.
  And if you need to download stuff in the daytime, just deselect the Enable Scheduler option.

So there you go, I have shared much of what I know, still if you need anything, just comment it.

In continuation of my previous post, I am putting up this guide to explain Port Forwarding. Note, this is something you should do only if you have done this. Also you will have to perform these given steps every time you turn on your UT Starcom UT300R2U ADSL Modem. Well who said speed comes easy ?

Here goes.

• Goto Start – Run, type into it “telnet 192.168.1.1″, without the quotes. It opens the command prompt, with the  following . For Linux users, type the same from terminal/konsole.BCM96338 ADSL Router
  Login:

  The login and password both are admin.

• Once it gives you the prompt (>_), paste the following lines. What it means is explained later.
  iptables -I PREROUTING -t nat -p tcp --dport 8080 -i ppp_0_35_1 -j DNAT --to 192.168.1.11:8080
iptables -I FORWARD -p tcp -d 192.168.1.11 --dport 8080 -i ppp_0_35_1 -o br0 -j ACCEPT
iptables -I FORWARD -p tcp -s 192.168.1.11 --sport 8080 -i br0 -o ppp_0_35_1 -j ACCEPT
  The above three lines mean, a) Accept packets from any source to my computer, b) Send packets from my computer to any destination.

• Make sure of 3 things
  1. Here 192…11 is my IP address. Substitute yours in that place. eg 192.168.1.10
  2. 8080 is the port that I have specified in my torrent client to be forwarded. Change them so that both are the same.
  3. Dont be a Pirate !

• There maybe a problem though. It may happen that your IP address changes everytime you switch on your Modem. So int the Start – Run menu, type ipconfig and see your IP address. Accordingly make changes to the above three lines.

Happy S(p)eeding !
