IP Address
There are two modes to operate the HT502:
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 HT502 acquires its IP address from the first
DHCP server it discovers from the LAN it is connected. Using the PPPoE feature: set the
PPPoE account settings. The HT502 will establish a PPPoE session if any of the PPPoE
fields is set.
Static IP mode: configure the IP address, Subnet Mask, Default Router IP address, DNS
Server 1 (primary), DNS Server 2 (secondary) fields. These fields are set to zero by
default.
