Viewing Current DHCP Address Assignments

When the Internet Security Router functions as a DHCP server for your LAN, it keeps a record of any
addresses it has leased to your computers. To view a table of all current IP address assignments,
DHCP Server Configuration page. A page displays similar to that shown in Figure 5.2; the bottom half of the
same page shows the existing DHCP address assignments.
The DHCP Server Address Table lists any IP addresses that are currently leased to LAN devices. For each
leased address, the table lists the following information:

Table 5.2. DHCP Configuration Parameters

Description
Specify the lowest and highest addresses in the DHCP address pool.
Enter the subnet mask to be used for the DHCP address pool.
The amount of time the assigned address will be used by a device connected
on the LAN.
The address of the default gateway for computers that receive IP addresses
from this pool. The default gateway is the device that the DHCP client
computers first contacted to communicate with the Internet. Typically, it is the
Internet Security Router's LAN port IP address.
The IP address of the Domain Name System server to be used by computers
that receive IP addresses from this pool. The DNS server translates common
Internet names that you type into your web browser into their equivalent
numeric IP addresses. Typically, the server(s) are located with your ISP.
However, you may enter LAN IP address of the Internet Security Router as it
will serve as DNS proxy for the LAN computers and forward the DNS request
from the LAN to DNS servers and relay the results back to the LAN
computers. Note that both the primary and secondary DNS servers are
optional.
The IP address of the WINS servers to be used by computers that receive IP
addresses from the DHCP IP address pool. You don't need to enter this
information unless your network has WINS servers.
