22.1 Checking the Ports After Port Forwarding
Once you have forwarded the necessary ports on your router, you should
check to make sure they have been correctly forwarded.
1. Go to http://www.yougetsignal.com/tools/open-ports/ .
2. Type in port 9000 and select the Check button to see if the port
tests as open or closed.
3. Type in port 2051 and select the Check button to see if the port
tests as open or closed.
4. All ports should be open, as shown in the example below.
5. If any port tests as closed, that port is not forwarded correctly.
Write “your external address” in the Information Log at the end of
the manual.
