aMule lowid, however 4662 seems to be open

[pmatos]

Hi all,

I'm working behind a USR 8003 router. 4672 and 4662 have forwarding enabled by the router. Everything is fine in my brothers PC (winXP+eMule) but in my system (Gentoo+aMule) can't connect to 4662. Can't even pass the test at http://www.amule.org/testport.php?tcpport=4662. Well, in ethereal I see router lets packets to 4662 pass.
I get:

Code: Select all

# nmap -sT -vv -p 4662,4672 localhost 

Starting nmap 3.81 ( http://www.insecure.org/nmap/ ) at 2005-07-21 16:09 WEST
Initiating Connect() Scan against localhost (127.0.0.1) [2 ports] at 16:09
Discovered open port 4662/tcp on 127.0.0.1
The Connect() Scan took 0.00s to scan 2 total ports.
Host localhost (127.0.0.1) appears to be up ... good.
Interesting ports on localhost (127.0.0.1):
PORT     STATE  SERVICE
4662/tcp open   unknown
4672/tcp closed rfa

Nmap finished: 1 IP address (1 host up) scanned in 0.126 seconds
               Raw packets sent: 2 (68B) | Rcvd: 2 (56B)

And I can telnet it:

Code: Select all

# telnet localhost 4662
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.

Any ideas what might be happening, since I'm always getting a lowid.

pmatos,

Your router will be doing Network Address Translation (NAT), to share a single publicj IP among several computers.
When you use NAT you can only forward a single port to a siingle IP inside the router.

You and your brother cannot both have high IDs at the same time unless you can find a client that does not use 4662 and 4672

shouldn't 4662 be udp rather than tcp?
