Is my port really closed?

[DubO]

Just got a new Belkin N+ F5D8235-4 router with my MacBook Pro 17, OS 10.8.2. Transmission 2.75 (13665).

UPnP is enabled, automatically map port is on, port forwarding and static IP address is set up in router and laptop. But my port, 60410, still shows as closed in the network preference pane. But in the log, it says the port is forwarded:

So, is my port really closed? Or is it open and the Belkin router is confusing Transmission? Or is Transmission buggy? Any help is appreciated!

Same problem with 10.8.2 and Transmission 2.7.5. Just started when upgraded to Mountain Lion

I have the same problem, seemingly, but I am on 10.6.8 with a new Airport Extreme set to the same profile as my old Airport Extreme.

As posted in this thread, the log says that the port was successfully opened, but the preferences pane show that the port is closed.

now, if only I could understand the search that x190 suggests.

I'm having the same problem...

That's the transcript from the message log, which looks like the port is forwarded correctly. However, it is still saying "Port is closed" in the network tab of my preferences. What's going on?

When I probe the port at the GRC site, it tells me the status is "STEALTH"...

On canyouseeme.com
Error: I could not see your service on MY IP on port (4654)
Reason: Connection timed out

However, I get the same thing with port 80 and port 21. Is it a firewall issue?

[NoobinLULZ]

Check Message Log (Debug). Is 4654 listed? Do you have a second NAT device? Is your router firewall level set appropriately (usually 'Low")?

2012-12-28 19:48:49 -0700 net.c:558 [Debug]Transmission: Bound socket 12 to port 4654 on 0.0.0.0

I posted exactly what was in my message log in blue. Yes, 4654 is listed. I don't believe I have a 2nd NAT device... It's just my Motorola Surfboard modem, Apple Airport Extreme router, and my computer. I know my NAT is open because I just played Call of Duty today, and it needs an open NAT for matchmaking. There are no firewall levels to set with the Airport that I can see with Airport Utility.

I have been using Transmission with this set up for about 3 years now without a problem. I am on version 2.75.

Perhaps viewtopic.php?f=4&t=14255 will explain this observation.
