IP Address 
The GXP21xx operates in two modes: 
1.  DHCP mode: all the field values for the Static IP mode are not used (even 
though they are still saved in the Flash memory.) The GXP21xx acquires its 
IP address from the first DHCP server it discovers on its LAN. The DHCP 
option is reserved for NAT router mode. To use the PPPoE feature, set the 
PPPoE account settings. The GXP21xx establishes a PPPoE session if any 
of the PPPoE fields is set. 
2.  PPPoE mode: configure all of the following fields: PPPoE account ID, 
PPPoE password and PPPoE service name. 
3.  Static IP mode: configure all of the following fields: IP address, Subnet 
Mask, Default Router IP address, DNS Server 1 (primary), DNS Server 2 
(secondary). These fields are set to zero by default.
