Setting up the DHCP Server 61

The Firewall can allocate up to 255 static or dynamic IP addresses. 3Com

recommends you use a dedicated DHCP server if more addresses are

required.

To set up the DHCP server on the Firewall click Network, and then select

the DHCP Server tab. A window similar to that in Figure 26 displays.

Figure 26 DHCP Setup Window

Global Options Enable DHCP Server

Click this check box to enable or disable the DHCP server. This is disabled

by default. Leave the DHCP server disabled if there already is a DHCP

server on the LAN or if manual addressing is used on the LAN computers.

Lease Time

This is the amount of time that the IP address is leased, or given to the

client machine before the DHCP server attempts to renew that address. If

the client still requires the use of the IP address, the DHCP Server grants

the client the use of that IP address for the same amount of time. If the

client no longer requires the IP address, the address is freed and returned

to the pool of available addresses to be used again. The default value is

60 minutes.

Client Default Gateway

Enter the IP address of the WAN router used by LAN clients to access the

Internet. If NAT is being used this will be the LAN IP address of the

Firewall.
