If the Automatically-assigned default gateway check box is selected, this gateway will accept the first received default gateway assignment from one of the PPPoA, PPPoE, or MER/DHCP enabled PVC(s). If the check box is cleared, enter the static default gateway and/or select a WAN interface. Press Apply to save it.
Note: If you select the Automatically-assigned default gateway check box, you must restart the router to obtain an automatically-assigned default gateway.
