Port Forward The Modem/Router - Right!

[Daffy D]

So the wifie seeing the latest offer from TOT and knowing I was thinking of getting a wireless modem went to the TOT office did all the paperwork and presented me with a shiny new WiFi Modem.

What a darling.

Anyway the nice lady at the TOT office set up the modem for her so all I had to do was connect it up and away we went.

All well and good but I download from Torrent sites so I need to have a Port Forwarded. I had a quick look through the pdf. manul that came on the disk, all 78 pages of it, but saw nothing about Port Forwarding.

Then tried the Simple Port Forwarding Program but my model was not listed.

All this time uTorrent was quite happily downloading and uploading so decided to check if my port, the setting from my old modem, was open and it was.

So here's the question if the Router/Modem has to be set with a port to forward how did my new modem know which port I was using and open it for me?

I'm just browsing through your settings and other assorted stuff now (nice video collection btw, do you speak japanese?) and it would appear that all your ports are open.

I had a similar experience when i got a new modem and switched to win 7.

It just worked after importing firewall rules and i dont question it.

Nice try

I checked a random selection of other ports and only the one was open

Ummm...

You don't need port forwarding to download torrents.

Port forwarding is to direct specific unsolicited incoming traffic to a specific IP on your internal LAN - for example if you're running a web server you'd direct port 80 to a specific machine, and ports 25 and 110 to another machine hosting email, port 53 to your DNS server, etc...

Your router "sees" which port you're running uTorrent on, so it directs the incoming traffic on that port to your IP without you needing to set up port forwarding. Prove it by changing the port uTorrent is using. It'll still work, without you needing to do anything at the router end.

If you look at your torrent client settings there is probably a check box labelled "use UPnP". Often this is ticked by defualt and allows your torrent programme to negotiate with your router as to which port to automatically open for torrents

Torrents will work without a port being opened but you will get better uploads with the port open which in turn will increase your share ratio and give you better download speeds.

false, this is only in case upnp is activated.

You'd be hard pushed to find a router from the last 10 years that doesn't do upnp and/or nat-pmp by default, which is why I didn't bother mentioning it. That's why I said 'Your router "sees" which port you're running uTorrent on, so it directs the incoming traffic on that port to your IP without you needing to set up port forwarding' which is basically upnp in operation, in layman's terms.

The OP was asking why he didn't need to set up port forwarding, I figured the answer above would be more useful than "because it's using upnp".

Yes the "UPnP" in uTorrent is activated, so this automatically opens the port on the router?

Good to know

Thanks

port forwarding automatically configured in most modern torrent programs?

If active in utorrent AND on the router then it configures itself.

Most routers and software are enabled by default now.
