3 Configuration Guide
To configure the GoIP4 Gateway, you must login to its Web server via the LAN or PC port.
The LAN port is factory preset to obtain an IP from the local DHCP host and the PC port is
set to the fixed IP 192.168.8.1.
If a local DHCP host is available, the LAN will obtain an IP address automatically. To listen
to the IP address assigned, just dial a call via the GoIP4 Gateway’s SIM card phone
number. When the call is connected, you will hear a dial tone. Just dial “*01#” for
English voice prompt on the LAN IP and “*00#” for Chinese voice prompt on the LAN IP.
The LAN IP Address can also be obtained by sending a SMS message to the GSM phone
number. The GoIP4 will then reply with a SMS message containing the LAN IP address.
If you want obtained LAN port IP by sending a SMS message, please send” INFO “or”
info”.
If a local DHCP host is not available, you can then access the GoIP4 Gateway via the PC
port. You will need to change your computer’s LAN configuration via the Network
Connections under the Control Panel.

Set an unused IP address that is in the same segment as the PC port address.
Once either the IP address of the LAN or PC port is known, you are now ready
to access the Web server of GoIP4 Gateway.
3.1 Web Configuration Menu
If your computer is connected to the GoIP4 Gateway via the LAN port network segment,
you need to type the LAN IP address of the GoIP4 Gateway in your Web Browser to access
the Web server of the GoIP4 Gateway. If not, you should type GoIP4’s PC port IP address
(192.168.8.1) in the Web Browser.
