3.11.2 PC Port Configurations

The PC Port allows addition network devices to be attached behind the GoIP4 Gateway.

It offers both Bridge and Static IP modes to meet your network topology. It is factory

preset to the Static IP mode with the IP address 192.168.8.1.

1） Bridge Mode

Select Bridge mode if your network topology requires the network devices (PC or

others) to be in the same network segment as the GoIP4 Gateway. In this case, the

GoIP4 Gateway functions as an Ethernet Switch.

2） Static IP Mode (Default Setting)

Select Static IP mode for a new network segment for the network devices behind the

GoIP4 Gateway. In this case, the GoIP4 Gateway functions as an Ethernet Router.

Fill in the IP Address field with a new segment address that is different from that for

the LAN port. Please select the Subnet Mask accordingly. A commonly used value

is 255.255.255.0.
