How to tell which ports are in use?
 

I'm trying to connect a bunch of cameras to a (Linksys WRT54) router,
and see them from my office. Aside from randomly choosing different
port numbers until each one works, is there a way to see which port
numbers are free? For example, 81 was ok, 8081 and 8080 are ok, but 82
and 83 appear to have some conflict (though still work).

Many thanks!

Reading between the lines and patching in the missing information I
think you are saying the following:-

You have several IP cameras on private IPs behind a NAT router with a
single public IP.
To access each camera's web interface remotely via the single public IP
you need to map various ports such as 80,81,82,83,84 to port 80 on the
internal IP of each camera. For example:-

81 - 192.168.0.1:80
82 - 192.168.0.2:80
83 - 192.168.0.3:80

You are finding that you get an error message when you try to open
certain ports (Although you don't say what or where).

You also fail to tell us what cameras you are using so I can't
investigate the manuafacturers site for information on how one might do
this.

Firstly I'd set up a VPN if possible and then connect directly to the
IPs. Secure and simple.

What services do you have open already on the router for ports 82 & 83?

Nice try, not even close though.


To the GG'ing OP:

Try Angry IP Scanner to get a report on ports in use.

See here before choosing your ports for the ipcams.

You can only see which port numbers are in use. You can't see what port
number will be used by a process until that process gets loaded and
listens on a port (other than look at the configuration for the
program).
