To configure the DHCP server, follow these instructions.
• Check the Enable DHCP Server for this Subnet checkbox.
• Enter the Gateway Address to issue the DHCP clients. If this field is left blank, the
CyberGuard SG appliance's IP address is used.
• Enter the DNS Address to issue the DHCP clients. If this field is left blank, the
CyberGuard SG appliance's IP address is used. Leave this field blank for automatic
DNS server assignment. If your CyberGuard SG appliance is configured for DNS
masquerading, you should either leave this field blank, or enter the IP address of the
LAN port of the CyberGuard SG appliance.
• Optionally enter a Domain Name suffix to issue DHCP clients.
• Optionally enter IP address of the WINS server to be distributed to DHCP clients in
the WINS Address field.
• Enter the Default Lease Time and Maximum Lease Time in seconds. The lease
time is the time that a dynamically assigned IP address is valid before the client must
re-request it.
• Enter the IP address or range of IP addresses (see the appendix entitled IP Address
Ranges) to be issued to DHCP clients in the Address Range field.
Click Finish.
