Port forwarding is required so that the router can forward data packages that arrive from the internet at a specific port (by default port 7610 for BarcodeChecker) to the one PC in the local network, which runs the BarcodeChecker software as server.

Without port forwarding, the server PC cannot be reached over the internet!

It is recommended to connect the scanners directly to the router (local LAN or WIFI) because this does not require a port forwarding. Moreover, a local network is faster and more reliable.


1.) Create DHCP reservation and Port Forwarding on router

1.) Login to your router.

2.) Set a DHCP reservation for your server PC to assign it a permanent IP address.

3.) Set a port forwarding to send all incoming traffic from the selected port to the server PC.


2.) Check Port Forwarding in the BarcodeChecker server

1.) Start the BarcodeChecker software as server on the PC and open a BarcodeChecker file.

2.) Check Allow internet access and select Connection over the internet.

3.) Click Check accessibility of server to test port forwarding.
