Changing Port function to “LAN” disables automatic IP address detection. If Port function is set to the default value “auto”, the Ethernet LAN port tries to automatically obtain the IP address using DHCP when the device boots. If the DHCP discovery fails, the device automatically uses IP address 10.10.10.10.
Note: Change the following setting before changing any other Ethernet settings.
- In the left pane, under Network, click Ethernet Port.
- Set Port function to LAN.
- Click Submit to save the settings.
If the functional mode of the Ethernet port is set to "WAN" or "VLAN", the following details must be noted. Before changing the Ethernet port mode to "WAN", the firewall configuration needs to allow Web UI and SSH access from WAN ( and enable both Allow WebUI access from WAN and Allow SSH access from WAN). The VLAN functional mode of the Ethernet port requires an external VLAN switch.
