am off sify and life is so good now.dunno whetheer this has been discussed before.jus outta curiosity. during my sify term, i checked with many softwares which have failed to recognize any open ports except for 25 and 110 tcp(which i suppose are for outgoing mail and stuff) and no udp.while azureus always shows that almost all ports are open and the bbimpsec allows users to open blocked ports, as in all the ports were really open!can the guru's confirm whether the ports are really open or what.

I think SIFY uses UPnP in their gateways. Hence when requested by applications which use UPnP protocol (like Azureus) , the gateways of Sify forward those ports to ypur computer. But if you check just like that , no port will be shown open. Same applies for the DSL routers. There is a way to enable UPnP in them too.

I would say that the ports are closed mateys !!!!! Coz i hav fought with the cc execs for over 1 week and in the end they opened them for me !!!!!!!! They do close them from the back , and they dont know how to open them !! I talked to a guy who said that he was the person who handeles firewall n all for all of sify , nd he said the ports r open !!!! Later on he himself called , apologised nd said the ports WERE closed due to the firewall !!! So then the opened and it is showin opened !! U can check ur port status at "https://www.grc.com/x/ne.dll?bh0bkyd2"If it shows stealth , that means the ports r closed !!! If it shows open or closed , then the ports aint blocked And by the way , Azureus requires ports 6881-6889 to work !!!!!!! :)

lol no dude . sify's has ultimate stupid lan system . They dont use upnp or anything at all as it is not completely NATing connections behind one internet ip .

Azureus doesnt need ports 6881-6889.
it can work from any port you specify in the settings , provided its not blocked by any firewall.
On the contrary , many trackers ban clients using the default 6881-6889 ports , as these ports are throttled by many ISP's , and using these ports reduces the swarm speeds.
So if at all anyone is using these ports, shift to a port higher than 50000.

thats ture but the problem is sify ass*oles DO NOT open any port above 5000 or anything . i have extensively checked from online scanners ( like grc) they can access only port 80,22,23 on my pc . rest all are blocked right at isp end ( i shut my fwall before testing ) . if i use port 80,22,23 then torrent client runs ok but when i change to any other i get NAT error bcoz port is blocked . So when on private tracker i cant use port below 1025 :( and 6881-6889 and i stick to any random higher port with nat error but after sometime it does connect to peer and dload goes at good speed ( just takes more time ) . on public trackers port 22,23 works mostly .

I dunno man , but from wat i have seen on torrent guides , ports 6881-6889 are the ones in which torrents r the fastest !! I could be wrong , but this is not discussion for torrents !! Its for ports !! And port 80 is open only coz if dey close it too, no one would b able to surf !!! The b*@tards !!! Well , try contactin the cc's if u hav time to waste , u mite b able to argue them to open them , like they did for me !!! And they really do open them !!!!!!
