Using the Firewall as a DHCP server
By default, the firewall functions as a DHCP (Dynamic Host Configuration Protocol) server,
allowing it to assign IP, DNS server, and default gateway addresses to all computers connected to
the firewall's LAN. The assigned default gateway address is the LAN address of the firewall. IP
addresses will be assigned to the attached PCs from a pool of addresses specified in this menu.
Each pool address is tested before it is assigned to avoid duplicate addresses on the LAN.

the firewall's LAN. The assigned default gateway address is the LAN address of the firewall. IP
addresses will be assigned to the attached PCs from a pool of addresses specified in this menu.
Each pool address is tested before it is assigned to avoid duplicate addresses on the LAN.
For most applications, the default DHCP and TCP/IP settings of the firewall are satisfactory. See
“Internet Networking and TCP/IP Addressing” in
“Internet Networking and TCP/IP Addressing” in
explanation of DHCP and information about how to assign IP addresses for your network.
If another device on your network will be the DHCP server, or if you will manually configure the
network settings of all of your computers, clear the Use router as DHCP server check box.
Otherwise, leave it checked.
network settings of all of your computers, clear the Use router as DHCP server check box.
Otherwise, leave it checked.
To specify the pool of IP addresses to be assigned, set the Starting IP Address and Ending IP
Address. These addresses should be part of the same IP address subnet as the firewall’s LAN IP
address. Using the default addressing scheme, you should define a range between 192.168.0.2 and
192.168.0.253, although you may wish to save part of the range for devices with fixed addresses.

The firewall will deliver the following parameters to any LAN device that requests DHCP:
•
An IP address from the range you have defined
•
Subnet mask
•
Gateway IP address (the firewall’s LAN IP address)
•
Primary DNS server (if you entered a primary DNS address in the Basic Settings menu;
otherwise, the firewall’s LAN IP address)
otherwise, the firewall’s LAN IP address)
•
Secondary DNS server (if you entered a secondary DNS address in the Basic Settings menu
Using Address Reservation
When you specify a reserved IP address for a PC on the LAN, that PC will always receive the
same IP address each time it accesses the firewall’s DHCP server. Reserved IP addresses should be
assigned to servers that require permanent IP settings.
same IP address each time it accesses the firewall’s DHCP server. Reserved IP addresses should be
assigned to servers that require permanent IP settings.
To reserve an IP address:
1. Click the Add button.
2. In the IP Address box, type the IP address to assign to the PC or server.
(Choose an IP address from the firewall’s LAN subnet, such as 192.168.0.X.)
