Port forwarding enables you to access the x500 IoT gateway’s LAN network (machine network) from inside the local corporate network. This way you can locally access the machine’s PLC, HMI, or other hardware, without having to set up a VPN connection first.
How it works: when you are inside the local corporate network, you access the x500 IoT gateway’s WAN IP address at a specific network port (i.e. 5900 for VNC traffic). The x500 IoT gateway’s port forwarding will then forward the network traffic to a target IP address and network port, resulting in a connection with the target device (PLC, HMI, or other).
The next steps show you how to add port forwarding.
- Go to [Devices] in the main menu, select the concerning device, open its [Config] tab, and edit the firewall settings.
- Press [Add port forwarding].
- Enter the external port, target IP address, target port, and press [Add].
