How to determine if a port is really opened on the router #159

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Please advise how to determine if a port (or a range of ports) has been really 
openned by the router. So any reported "port closed" issues by kinds of 
downloader clients can be safely claimed to be the faults of the clients 
themselves, either due to bugs or errors in configurations. I tried every means 
to open and forward the peering ports for Transmission 2.5 on RT-N56U, but this 
client never stops complaining "port closed". Thanks a lot!

Hi,

You can see the opened / forwarded ports here 
http://my.router//Main_IPTStatus_Content.asp

and also in the terminal:

# netstat -tupln

This will show listening TCP and UDP ports. See netstat --help for more info.
