The following information is required:
Interface: Interface on which IPv4 DHCP server is to be configured.
Lease Range: Range of IP addresses that the DHCP server should allocate to the clients.
• Range Start: Start of lease IP range.
• Range End: End of lease IP range.
Lease Time (Optional): The duration of the lease of the IP addresses.
Gateway: IP address of the router (default gateway) that the clients should use to communicate with clients on other subnets.
Subnet Mask: Subnet mask to be used by DHCP server to identify whether the IP address to assign belongs to the subnet.
DNS (Optional): IP address of the DNS server that the clients should use to resolve domain names.
• Primary DNS (Optional): Primary DNS.
• Secondary DNS (Optional): Secondary DNS.
WINS (Optional): IP address of the WINS server that clients should communicate with to register and resolve NetBIOS names.
• Primary WINS (Optional): Primary WINS.
• Secondary WINS (Optional): Secondary WINS.
Once your changes are done, you need to start DHCP Service from Configuration -> DHCP Server -> Start DHCP Service to reflect the changes.
The following information is needed to set up DHCP Server IPv6 configuration
Interface: Interface on which IPv6 DHCPv6 server is to be configured.
Lease Range: Range of IP addresses that the DHCPv6 server should allocate to the clients.
• Range Start: Start of lease IP range.
• Range End: End of lease IP range.
Preferred Time: Length of time that a valid address is in the preferred state and can be used without any restrictions. When the preferred-time expires, the address becomes deprecated. A deprecated address should not be used for new communications, but might continue to be used for existing communications in certain cases.
Note: If the valid-time is also configured, the preferred-time must be less than the valid-time. The preferred-time and the maximum-lease-time are mutually exclusive and cannot both be configured.
DNS (Optional): IPv6 address of the DNS server that the clients should use to resolve domain names.
• Primary DNS (Optional): Primary DNS.
• Secondary DNS (Optional): Secondary DNS.
Note: Once your changes are done, you need to start DHCP Service from Configuration -> DHCP Server -> Start DHCP Service to reflect the changes.
You have successfully configured DHCP IPv4/ IPv6 server on your firewall.
