shzulu Posted March 17, 2007 Report Share Posted March 17, 2007 hi!i have the following prob:1. i have wireless connection and im using ovislink wl-5460ap v2 access point2. my isp say we're all behind nat. thats ok.3. im not using any firewall (on xp x64 sp3)4. i can dl with utorrent no problem5. i always see red circle with white exclamation mark in it (Not connectable. A firewall/Router is limiting your...)6. i did online port scaning and found that tcp ports 23, 2000, 2222 and 3986 are open.7. i set utorrent to use these ports and check every one of them on http://www.utorrent.com/testport.php and it said their all open8. but the not connectable mark still remains active.i tried turning on/off upnp port mapingi called my isp and they told me they wouldnt open ports for me, ie i have to pay extra for static ip.now, for my question, are the above mentioned ports really open? if yes, how can i set up utorrent to use one of those ports.thanks!

Switeck Posted March 17, 2007 Report Share Posted March 17, 2007 If your ISP tells you that you're behind NAT and they won't forward ports for you...you are guaranteed firewalled in µTorrent and there's nothing you can do from your computer to change that...at least if UPnP doesn't work.

shzulu Posted March 18, 2007 Author Report Share Posted March 18, 2007 well, then, thanks yor your replies, guys.but, still, #6/7 of my post above bother me. Link to comment Share on other sites More sharing options...
Switeck Posted March 18, 2007 Report Share Posted March 18, 2007 It really depends on what the port checker sites mean by an open port.Can you connect outward on that port?Can you connect outward TO someone ELSE on that port?Can someone else (on any port) connect TO you on that port?Only the last one of those 3 would be blocked by a firewall or being behind NAT.

shzulu Posted March 18, 2007 Author Report Share Posted March 18, 2007 well, i guess those open ports are open at my isp, not at my side. Link to comment Share on other sites More sharing options...
hanssen Posted July 19, 2007 Report Share Posted July 19, 2007 I disagree here. There's a strange problem that I've noticed:On the exact same hardware, using the exact same modem/router (Thomson SpeedTouch 780WL) and Network Card, Windows 2000 does NOT do the same as Windows XP x64.In Windows 2000 µTorrent turns Green,in Windows XP x64 it will stay Yellow.Using the exact same open port.Also, with the Yellow icon never turning Green I haven't noticed ANY slowdown in XP x64. I really wonder what is causing this, since I have tried everything. Firewall and entire Security center is off in XP. No virus-scanner, no packet-filtering or blocking.Anyone also using a Windows XP x64 version and seeing this Yellow icon issue? I do know that, for example PeerGuardian really needs a different set of drivers for it to work in x64, which is why you can get a separate x64 version of pg2.So, unfortunately, I'm pointing at µTorrent for this bug for now.Regarding this; What is µTorrent checking for, before turning Green? It seems it does not match reality in all x64 cases.. Link to comment Share on other sites More sharing options...
Ultima Posted July 19, 2007 Report Share Posted July 19, 2007 Using the exact same open port.Simultaneously? Without modifying the router rules? Link to comment Share on other sites More sharing options...
hanssen Posted July 21, 2007 Report Share Posted July 21, 2007 Yes, unfortunately.The *only* difference is the NIC drivers. (64 bit for one, 32 bit for the other)I could check using ethereal/wireshark if I see something strange on this.But that is why I ask:What is the exact check µT does in order to change from Yellow to Green ?

Ultima Posted July 22, 2007 Report Share Posted July 22, 2007 Um. If you're using the same port simultaneously on two computers, then isn't it clear why one computer receives the connection while the other doesn't? You can only forward each port to one computer.The only thing µTorrent needs is for an incoming connection attempt to hit it, and it knows it's unfirewalled.

hanssen Posted July 24, 2007 Report Share Posted July 24, 2007 I don't think you understand. What port I'm using is of no importance here.I have tested this using two different machines BOTH running two operating systems. At first I thought: Well, probably the hardware (NIC) is broken on one of them. It wasn't. It turns out to be dependant on Windows XP x64 (or its drivers).Again I ask:What is the exact check µTorrent does in order to change its icon color from Yellow to Green.As long as I don't know that, I can't resolve this issue.I need to see what goes wrong, using ethereal/wireshark, and in order to be able to see that, I need to know what uT is checking on. I see nothing wrong. Torrent traffic is just as it should be. Maxing out upstream as well as downstream, yet it remains Yellow. Link to comment Share on other sites More sharing options...
Switeck Posted July 25, 2007 Report Share Posted July 25, 2007 Windows XP x64 may have a different half open max than regular Win XP. Link to comment Share on other sites More sharing options...
Ultima Posted July 26, 2007 Report Share Posted July 26, 2007 @hanssen: I understood you the first time, but you're not reading/answering my posts clearly.I asked you if you were using the same port on both computers simultaneously, and you said yes, and so I interpreted that to be a possible cause for the firewalled issue.You asked how µTorrent determines when to switch the network status light, and I answered youThe only thing µTorrent needs is for an incoming connection attempt to hit it, and it knows it's unfirewalled.

hanssen Posted July 27, 2007 Report Share Posted July 27, 2007 Well, you make the strange assumption I'm using the same port on two LAN IP's at the same time?It would not even turn Yellow then, as far as I know..Hitting an incoming connection does not make it turn Green, so that's NOT what µT is checking for. That's WHY I'm here asking this.How can it even be transferring as it should while there are, according to your statement, NO incoming connection hits?And the half-open max is not of importance either (I've already patched tcpip.sys).Bumping this, since I still see no change in the yellow icon on my end of the line.As I've written before: This is related to uTorrent in Windows XP x64. I'll say it's a bug in Windows!I don't have it in any other Windows OS (but I haven't tested Vista either).The Yellow icon does not turn green, yet the port is correctly being forwarded (the modem is a SpeedTouch 780, and it links open ports to the PC-name, even, so you can't go wrong there). It's a clean XP install, in which I have switched off the entire security end of things. No firewall active, no other software doing this, it's just plain uTorrent.
