Ok, lets suppose I found something perfectly legal but needed to use a Torrent to get it.
However my machines ports are all apparently blocked. No firewall seems to be enabled.
How can I enable a Torrent downloader such as Azureus to work. Every time I enter a port I get an NAT error and it won't connect.
Thanks :)
-
you've checked that built-in one as well, haven't you?
try changing ports in azureus as a last resort.
-
There doesn't seem to be any kind of firewall enabled (at the moment anyway) and everything else including online games, Kazaa Lite and MSN Messanger seem to run fine.
-
maybe the tracker is down? that happens just too often.
-
If you should happen to be following the trend and downloading Civ3 from suprnova, the tracker is ****ed, apparently.
But to disable the inbuilt firewall: Open the Network Connection status window thing (the one that counts packets recieved and sent), Properties, Advanced, uncheck the firewall box.
-
That's the problem - I'm not trying to get that - I'm after something else.
And I'm not sure if trackers have anything to do with it. As I said I got Azureus so I could specify what port to use, now the damn thing comes up with NAT error every time I try and test a port for usefulness.

you're behind a router.
what kind of router?
-
check this out... might help. if you need any more help, like with port forwarding or what have you, let me know
http://www.dessent.net/btfaq/#ports
just for reference: TCP 6881-6889, 6969 for older versions, TCP 6881-6999 for newer. this info could be wrong, i can't remember too well.
-
why is that on dessent.net? :wtf:
-
why shouldn't it be? do you have a problem with it being on dessent.net?
-
Eugh... this is where my headache starts. I am behind a router and do have an NAT (according to this: http://www.u.arizona.edu/~trw/games/nat_or_not.php)...
The router/modem is an Alcatel Speedtouch 510. I've got into the properties for it but can't find anything regarding ports. I get a control panel looking like this but the rest I'm not to sure about (and indeed hesitant to change due to lack of knowledge).
-
Look for port forwarding settings, set the port to 6881 and the ip to the one you use in your BT computer. You may also need to set a permanent IP for that computer to prevent it getting any other IP's.
Read the router's manual. :)
-
well if you have more than one computer behind the router, check your IP address (Start --> Run --> Command --> "ipconfig") and see if it's one of the RFC1918 "private addresses"... chances are it'll be a private C: 192.168.***.***. if so, then you know your router has NAT. most home routers do, that'd kind of the point of them. and NAT usually works hand-in-hand with PAT (hence the "NAPT")
I knew you were behind a router, because that's a typical problem you're having from behind a router.
Remember those ports i gave you (check my previous post, or the one before it) well those are the ports Bittorrent communicates on. i'm pretty sure anyway, i remember reading about it a while ago, although i've never used Bittorrent personally. What's happening at the moment, is your router's NAT firewall is blocking those ports. the router doesn't know what computer to forward information coming in on those ports to. Now what i'd recommend doing, is set a static IP address for yourself on the router, so your IP address will never change. when you get that working, there should be something in your router command webpage thingy to do with Port forwarding, translation, Firewall, etc. In one of those, there'll be a screen that looks something like this:
(http://www.swooh.com/lorenzo/portforwarding.JPG)
as you can see basically it binds a port to a certain computer. you want to make sure your computer's on a static ip address though, in case your router's DHCP assigns you another address, which is unlikely, particularly if you're using only one computer through the router, but possible. Have you ever wondered why "Direct connect" doesn't work on AIM when you're behind a router? well this is why.
Now that you understand the concept, I took the liberty to do some research for you regarding port forwarding on the Alcatel 510, which i'm not familiar with... this page describes in detail how to bind ports to IP addresses, follow its instructions, and you should be fine:

ehhhh you have to go to 10.0.0.138 to get into your router, right? that sucks. so in my previous post when i said "192.168.***.***" don't listen to that. it appears this router's probably going to assign a class A address, so your IP address locally will look something like 10.0.***.***.
same thing. basically as long as your local IP starts with 10, 192.168, or 172, then your router's using nat.

I normally wouldn't bump such an old topic but since I first created it and I don't like reposting things - well here it is again.
I'm getting NAT errors. I'm on a wireless ethernet adaptor to an Linksys Wireless-G Broadband Router. I have port forwarding enabled in the router setup screen and I have my firewalls (XP is turned off, I'm using ZoneAlarm) setup to allow the correct ports. Azureus still gives me NAT errors and it seems that disabling ZoneAlarm doesn't have any effect on proceedings. Neither does repairing my connection to establish a new one.
Does anyone have any ideas? I can't think of anything else to look at and I have been reading through every guide on the subject that I can get my hands on...

Did you already check our shiny, new wiki? ;)
http://www.hard-light.net/wiki/index.php/BitTorrent_problems
-
oh, nice one, mr fury. almost as nice as saying STFW...
you 100% sure the router's set up correctly?
-
The wiki is there for people to read it. I merely pointed him to a helpful wiki article in a case he had missed it.
-
I use UPnP for **** like this. Simply tell Azureus what port you want it to use and it'll sort the router out itself. Too easy.
-
Upnp might not be setup correctly. THere is a free test utility that can diagnose problems.

some isp block those 6000 ports
try changing azureus to use port 55000
then forward that from the router
-
Sorry guys, I should've mentioned earlier that Mr Fury got on MSN and helped me sort out the problem (changing the port range to something totally different fixed this issue).
Thanks for all your help though :)
-
heh, seems like my tip from the first port workeded, then. but, eh, I wouldn't say it's last resort anymore. I tend to randomly change my port from time to time now.
-
That's just it.. by rights everything (should) have worked using port 8001 through 8009 but for some reason it didn't.
Meh... whatever. The whole thing does my head in sometimes but at least it's working for now. That's the main thing.
