If you are planning to run a DHCP server on IPCop you can configure the basic parameters at this time. Otherwise, do not enable the server, and Skip to setting passwords, below.
Dynamic Host Configuration Protocol allows computers to configure their network interfaces when they are booted.
You can delay setting up IPCop's DHCP server until after the installation completes. See the Administration Manual for a description of the web-based method of enabling and configuring the DHCP server.
Use the Space bar to select Enabled to enable the DHCP server.
The Start address and End address define a range of addresses that IPCop's DHCP server will assign to computers when they ask for an address. Do not use your full network range for DHCP. At a minimum leave out IPCop's address. A good range might be from 192.168.1.100 to 192.168.1.199. This will allow 100 concurrently connected devices on your GREEN network.
As a practical matter, at some future point in time you may wish to run servers that are only accessible from within your GREEN network. Whether you run file servers, mail servers, printers or any other service that needs a permanent address, these machines should be assigned IP addresses outside the dynamic DHCP range. A good range for them might be from 192.168.1.200 to 192.168.1.254.
DHCP works by passing out leases on dynamic addresses that expire after a certain period of time. Default lease time specifies the default lease time, in minutes, offered by the DHCP server. After the default lease time expires, the client computer will attempt to ask for a new lease for the address it acquired.
When you have finished with DHCP server configuration, select the Ok button to continue.
