Dhcp Server; Dhcp Client; Dns Relay - US Robotics 9108 User Manual

U.S. Robotics Wireless MAXg ADSL Gateway User Guide
explicitly let a remote technician access the gateway's WUI.
The user account can view the configuration parameters but not change them.
The support account does not work in bridge mode since there is no public IP address
assigned to the gateway.
The remote technical support user can read/write the configuration but cannot change
security settings. When remote access security is enabled by a local administrator, the
remote user can access the modem via telnet or a browser from the Internet, but not
from the LAN.
The maximum length for user names and passwords is 15 characters.

DHCP Server

The gateway provides DHCP server service over the LAN interface when the network
operating mode is set to PPPoE, PPPoA, MER or IPoA mode. When enabled, the DHCP server
responds to DHCP request packets from LAN devices and assigns:
An unused IP address within the start-end IP address range configured by the user to
the LAN device.
The gateway's LAN interface IP address as the primary DNS server address to the LAN
device. The ADSL gateway performs DNS relay between the LAN device and the real
DNS server at the remote service provider site.
The gateway's LAN interface IP address as the default gateway to the LAN device.

DHCP Client

The gateway provides DHCP client service for each Internet interface operating in the MER
network operating mode. If enabled, the DHCP client requests the WAN interface IP address,
primary and secondary DNS server addresses, and default gateway from the DHCP server at
the service provider site. If the DHCP client function is disabled, the user must manually
configure the WAN IP address, DNS server addresses and default gateway.

DNS Relay

The gateway provides DNS Relay service only when the NAPT function is enabled. It forwards
he DNS inquiry packets received from the LAN devices to the primary DNS server at the
remote site and vice versa. The DNS response packets received from the remote DNS server
are relayed back to the LAN device.
