Testing Port Forwarding

post #1 of 25
Thread Starter 
How can I test if a port is forwarded correctly? I have massive problems opening ports (god I hate Linksys) so I never really know if a port is really forwarded or if my router just wants to trick me into believing that it is. How can I test it?

That always reads not open. I suspect it's not right (I hope it's not right) so I'm looking for another way

Works fine for me. (Linksys router - WRT54G)

If you want port 6969 open on Linksys routers, I found out you can't just open that. You have to do 6968 to 6970 to open it, or it won't work.

Doesn't for me all the time either. Only sometimes does it work.

Or you could do the same Starting and Ending Range. (Same router as you, with DD-WRT v23 SP2)

Really? I'll try that. If it works - you will be on my list of my most favoritest people ever

**EDIT**
No dice. Still not open. I turned off my firewall to be sure it wasn't that - I really hate Linksys

You're still not one of my most favoritest people ever

I know. Thats what I did. If I wanted port 6969 opened:

From 6969 to 6969 = Not work
From 6968 to 6970 = Works

DD-WRT v23 Mini here, same deal.

Hmm, that's peculiar. It works for me.

By the way, I'm using v23 SP2 Standard on mine if that makes a difference.

Give this a try besides using utorrent. This will only work if you know the app or server name:
  • Go to the Start Menu -> "Run..."
  • Type "telnet server-name "PORTNUMBER". For example:
    telnet pop.uwm.edu 190
  • If the window lags while displaying "Connecting ..." and then goes away, the port is not accessible. If the window instantly goes away, the port may not be accessible. If the window displays something along the lines of "220 ESMTP ..." then the port is open.
  • If there are continual problems try again using the IP address of the system.
