From the gt704 home page click the
advanced setup icon
Click the
lan ip address link then change the modem ip address to 192.168.1.253
Click the apply button
Go back to the
advanced setup page
Click the
dhcp settings link
Select the off option
Click the apply button
Connect a gt704 lan port to a p-660 lan port and it's done
