How to open a port on firewall

I have a RV110W firewall installed. Now behind this firewall there is a server running. I need to access this server from outside of the store through a specific TCP port.

Physical connection from outside to the server is like this.

Outside -> Router -> Firewall -> Server

Router IP:

Firewall WAN IP:

Firewall LAN IP:

Firewall Gateway IP: 192.1681.1

Server IP:

The firewall is in gateway mode.

Now I forwarded a TCP port on router to firewall ( and on the firewall i forwarded the same port to server (

On the server system, i opened the port on windows firewall for inbound.

This there anything I am missing?

your steps seems to be fine at first look, but somewhere in that chain there is probably something broken.

  • what kind of service is on that server port?
  • are you able to open connection from outside with telnet to Router WAN IP and port? example test from outside/internet:
telnet X.X.X.X YYYY

where X.X.X.X is WAN IP of Router and YYYY is port number.

You can confirm that port forwarding is working on both devices:

  • you can try to connect with computer between Router and Firewall and try that port on firewall.
  • if previous test works, then for testing purposes move server to subnet between Router and Firewall and perform connectivity test from internet.
