Change the range so that it is:
Starting IP: 192.168.1.100
Ending IP: 192.168.1.254
That should fix an issue. I point to
Title/Location: portforward.com -> forum -› Knowledge Base -› How to choose a Static IP address
so I'm assuming that the inside computer is on a wire and that you set that computer to
192.168.1.22 with 255.255.255.0 and a gateway of 192.168.1.1 you ALSO OPENED PORT X on the firewall of this computer?
and that you went to the router 9100 and you told it to forward port X FROM ANY to 192.168.1.22 port X and that you saved it or "applied" it , then rebooted router and the settings are not there?
Check and see if windows firewall is blocking connections.
I thought port forwarding was broken for me until I saw that it was on, and once I turned it off the fowarding worked.
I tried a bunch of different things suggested on these forums but finally got some ports open:
From the main menu, go to "Firewall Settings" (click "Yes" to proceed)
Select "Port Forwarding" from the left-hand side
Click "+" to add a new port forwarding rule (or "New Entry")
Now, here's the tricky part:
Do NOT select either the "Specify Public IP Address" or "Specify Network IP Address" checkboxes.
Instead, type the local (LAN) IP address of the computer you wish to forward to in the box on the right-hand-side of Local host:
Do the other stuff (protocols, ports, etc.) and voila! (at least this worked for me...). Good luck.
Oh, and I've found that port 80 is not blocked in my service area.
You might want to see if you can narrow it down between a port forwarding (router) issue, an issue with the server's firewall or an issue with the application itself. On the computer that is listening on port 20715, you can test it by running at the command prompt (run->cmd):
telnet 127.0.0.1 20715
If it's working properly, you should see some sort of greeting string. For instance, this is the response from port 25 on my machine running MS Outlook:
telnet 127.0.0.1 25
220 xxxx.somedomain.com Microsoft ESMTP MAIL Service, Version: 6.0.2600.5512 read

If you get a response like this on port 20715, then at least you know the application is working. Next step, you might want to try the same thing from a different machine on your LAN to make sure your server firewall is not getting in the way. If you get past these two stages, then you're definitely stuck with a strange port forwarding problem.
Apologies if you're tried all this stuff already...
