The SMCWHSG44-G can automatically assign IP addresses to client comput- ers by DHCP. In this section of the management page, you can specify the Default gateway, Subnet mask, Primary DNS server, and Secondary DNS server settings that will be sent to a client at its request. Additionally, you can specify the first IP address that will be assigned to the clients and the number of allocatable IP addresses.

In most cases, Default Gateway and Primary DNS server should be set to the IP address of the Router's LAN interface (e.g., the default LAN IP address is 192.168.2.1), and Subnet mask is set to 255.255.255.0.

NOTE: There should be only one DHCP server on the LAN; otherwise, DHCP would not work properly. If there is already a DHCP server on the LAN, dis- able the DHCP server functionality of the Router.

ii. Static DHCP Mappings

Fig. 66. Static DHCP Mappings.

IP addresses of servers are often static so that clients can always locate the servers by the static IP ad-dresses. By Static DHCP Mappings, you can ensure that a host will get the same IP address when it requests one from the DHCP server. Therefore, instead of configuring the IP address of an intranet server manually, you can configure the server to obtain an IP address by DHCP and it is always assigned the same IP address.
