Hi,
I am trying to open a port on this ADSL router for uTorrent.
ifconfig returns:
-----------------------
eth0 Link encap:Ethernet HWaddr 00:0D:88:32:06:4A
inet addr:10.1.1.3 Bcast:10.1.1.255 Mask:255.255.255.0
inet6 addr: fe80::20d:88ff:fe32:64a/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:60362 errors:0 dropped:0 overruns:0 frame:0
TX packets:79294 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:31149012 (29.7 MiB) TX bytes:47084539 (44.9 MiB)
Interrupt:10 Base address:0x2000
-----------------------
I open a web browser and go to 10.1.1.1, Advanced, Lan Clients, and 10.1.1.3 is there as a static address.
I then go to port forwarding and, for connection pvc0, LAN IP 10.1.1.3, Category User, I add a rule:
Name Utor1: Protocol TCP,UDP, Port Start 12963, Port End 12963, Port Map 12963, then Apply.
I then highlight the new rule, and Add and Apply. I then save and reboot the modem.
I have also tried rebooting the server at this point.
My problem is, I run # nmap -v 10.1.1.3
and I think I should see the open port listed but I get this:
----------------------------
Starting nmap 3.81 ( http://www.insecure.org/nmap/ ) at 2007-03-03 19:34 EST
Initiating SYN Stealth Scan against 10.1.1.3 [1663 ports] at 19:34
Discovered open port 22/tcp on 10.1.1.3
Discovered open port 25/tcp on 10.1.1.3
Discovered open port 139/tcp on 10.1.1.3

Discovered open port 5520/tcp on 10.1.1.3
The SYN Stealth Scan took 0.16s to scan 1663 total ports.
Host 10.1.1.3 appears to be up ... good.
Interesting ports on 10.1.1.3:
(The 1656 ports scanned but not shown below are in state: closed)
PORT STATE SERVICE
22/tcp open ssh
25/tcp open smtp
111/tcp open rpcbind
139/tcp open netbios-ssn
445/tcp open microsoft-ds
1521/tcp open oracle
5520/tcp open sdlog
Nmap finished: 1 IP address (1 host up) scanned in 1.969 seconds
Raw packets sent: 1665 (66.6KB) | Rcvd: 3335 (133KB)
-----------------------------
A couple of questions;
Have I opened the port correctly?
If so, should I see this on the nmap list?
Should I have made any changes to iptables to accommodate this?
TIA
Steve
