Default
Gateway IP address of Default gateway for the router. When entering IP address
of default gateway, all packets for which the record was not found
in the routing table are sent to this address.
DNS server IP address of the primary DNS server for the router.
Table 9: Configuration of network interface
The DHCP server assigns the IP address, default gateway IP address, and IP address
of the DNS server to the connected DHCP clients.
The DHCP server supports both static and dynamic assignment of IP addresses. In
Dynamic IP address assignment, the DHCP server will assign a client the next available IP
address from the allowed IP address pool. Once the lease time on an IP address has expired,
the DHCP server is free to re-assign that IP to another client.
Item Description
Enable dynamic
DHCP leases
Select this option to enable a dynamic DHCP server.
IP Pool Start Starting IP address of the range allocated to the DHCP clients.
IP Pool End Ending IP address of the range allocated to the DHCP clients.
Lease time Time in seconds that the IP address is reserved before it can be re-used.
Table 10: Configuration of a dynamic DHCP server
The DHCP server can also assign a Static IP address to a client. The MAC address
of the client must be configured in the MAC address table along with the desired IP address.
Up to 6 static IP addresses are supported. Do not overlap the static IP addresses with the
addresses allocated by the dynamic DHCP address pool. Otherwise, incorrect network
functioning may occur.
