IP Address There are two modes to operate the HT502:

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.

Server 1 (primary), DNS Server 2 (secondary) fields. These fields are set to zero by
default.
