Network (in)Security Interesting hacks and cracks. Info on firewalls, TCP/IP, encryption, networks, and security. The ins and outs of the phone system, caller services, how things work, what's illegal and what's not, cellular phones, beepers, telephony legislation, the PUC, ISDN, taps, who's listening, and switches. Talking about phones, hacking systems, technical advice, and such is completely LEGAL in the United States -- it's covered by the First Amendment. What's illegal is conspiracy to commit a crime. So if you say something like "Meet me at 2am so we can crack a can" or "I changed my cell phone's number myself" you are criminally liable. Stating "You can crack a can by doing thus-and-so" or "If you wanted to change a cell phone's number, you could do it like so" is perfectly OK. Posting passwords, calling card numbers, or credit card numbers is forbidden on this network. Posting such info will get you booted off the net.

Trollism is a social construct
Default Just a simple question concerning local and remote add.

Just curious; why did my laptop utorrent connection went through a local connection, then remote connection before it reach outside connection ? Is it something firewall related or what ? Btw, I'm torrenting on guest account.

tl/dr:

utorrent---> 111.0.0.1:61111 (local add)---> 111.0.0.1:2040 (remote add) ----> free world.

Why won;t my utorrent just connect it's listening port to free world directly ?

Hey, I am not trolling here MadMad, really I want to know why is this happening ?

Under my AVG > Utilities > Connection, I can see my utorrent is going through 2 addresses while listening, why ????MadMad

Maybe you should ask the people who wrote uTorrent? I mean, how would we know why they made decisions?

It could be that the two different ports are for "legacy" versus "non-legacy" connections. Some torrent clients can only connect within a narrow range of ports. It's usually best to disable legacy connections and use encryption, however, IMO.

no, I mean why the listening port is connected to another internal remote address before it's going out ?

like for other incoming connections, it's local address (111.0.0.1:2111)-------> remote address (123.12.11.122),

but my listening port is connected to another "remote address" which is actually a local address. (111.0.0.1) being my local address. I don't understand why ...
