Why is a firewall icon shown while I can reach the port 6346? (Mac OSX 10.4.10)

[Anic297]

Hello,

This is my first post in this forum so I will try to be clear enough (and english is not my natural language...).

As suggested by the forum rules, I have looked at the previous posts to find a problem similar to mine. When I came to the 12th page, I thought the problem won't be mentioned and I gave up searching (it took several hours to reach the 12th page).

Here are the data about my attempt:

1. OS version?
Mac OSX 10.4.10

2. What firewalls you have?
One built-in the OS (deactivated for testing) and probably one in my router.

3. How much ram?
768 Mb

4. Hard Disk space available?
6 Gb

5. Connection type? (eg: dialup, broadband, cable, etc.)
ADSL (limited because of my geographical location; far away cities).

6. Modem & router brand name & model numbers?
USRobotics USR5461 (router)
ZyXEL Prestige 600 series (modem; delivered with the ADSL pack).

7. Where are you trying to connect from (house, appartment complex, school, student accomodation, work, etc.)?
House

8. What version of LimeWire (LW) & Java do you have? (Go to LW's menu Help>About LW...) Will show both LW & Java version.
Limewire: 4.12.14
Java: 1.5.0_07

9. Who is your ISP (Internet Service Provider)? Sunrise

10. Do this simple test for us. Using your browser go here: http://www3.limewire.com:6346/ The page should say 'Your test worked!'. What happens when you go there?
"Your test worked!"

11. Are you sharing the connection with other computers or p2p sharing programs? If yes, please give details of set up.
My computer is connected wirelessly on the router. Another computer, often used, is also connected but with an RJ45 cable.

12. Is this a your 1st try at LW or is this a new problem with an experienced user.
I used it with a 56k modem a long time ago.
It is my first try with adsl.

13. Do you see a brick wall in front of the blue world icon at the bottom of LW's interface?
Yes

14. For those using a modem/router, how is your modem/router set up...are you port forwarding or is UPnP enabled?
I was not able to figure out if my router supports UPnp so I set DMZ to the IP of my wireless-connected computer.
In the preferences of Limewire, under the "Firewall" place, I have set "Listen on port" to "6346" and "Manual configuration" (sorry, I don't see the english terms so I try to translate; this is the 2nd radio button) to "6346".

15. What security programs are you using (antivirus etc)? Some people might not be aware that their security suite includes a firewall
None

16. What country are you living in? Sometimes there are ISPs with the same name in more than one country (eg Clearwire in the USA & also in Ireland).
Switzerland

I'm trying to understand the problem. There is a firewall icon in the bottom of the window (limewire) but I can reach http://www3.limewire.com:6346/. That should mean the port 6346 is open, correct? So why is the Firewall icon appearing if the port is open?

Thanks in advance.
