Network Connections Section

Lease Time In Minutes

: Each device will be assigned an IP address by the

DHCP server for this amount of time, when it connects to the network. When the
lease expires the server will determine if the computer has disconnected from
the network. If it has, the server may reassign this IP address to a newly-con-
nected computer. This feature ensures that IP addresses that are not in use will
become available for other computers on the network.

Provide Host Name

if Not Specified by Client

: If the DHCP client does not have

a host name, the gateway will automatically assign one for him.

DHCP Relay.

Your gateway can act as a DHCP relay in case you would like to

dynamically assign IP addresses from a DHCP server other than your gateway's
DHCP server. Note that when selecting this option you must also change
Router's WAN to work in routing mode.

1.

After selecting 'DHCP Relay' from the drop down menu, a 'New IP Address' link
will appear: Click the 'New IP Address' link. The 'DHCP Relay Server Address'
screen will appear.

2.

Specify the IP address of the DHCP server.

3.

Click 'OK' to save the settings.

Disabled.

Select 'Disabled' from the combo-box if you would like to statically

assign IP addresses to your network computers.

LAN BRIDGE >> ROUTING

You can choose to setup your gateway to use static or dynamic routing.
Dynamic routing automatically adjusts how packets travel on the network,
whereas static routing specifies a fixed routing path to neighboring destinations.
