DHCP
On the Local Network DHCP subpage you can enable/disable
Dynamic Host Control Protocol and set the Address ranges from
which the addresses are distributed to the DHCP clients on your
network. You can also set the Domain Name Server addresses here.
Start address is the first address in the address range. The Range size
defines how many addresses the range contains. Subnet mask is the
subnet mask of the addresses in the range. Primary and Secondary
DNSs set the domain name servers for the corresponding address
range. Lease time defines how often the DHCP client must renew its
lease. Domain name defines the domain name for the range.
The DHCP server can be enabled towards LAN, WLAN and
VBRIDGE (gateway interface) ports. When the DHCP server is
enabled, up to two scopes (address ranges) are automatically
generated and bound to LAN/WLAN/VBRIDGE interfaces, in this
order if the interface has an IP address. If your LAN and WLAN
interfaces have separate IP addresses you must configure two address
ranges, one for each interface. In Figure 5-10, scope (a) has been bound
to Ethernet interface and scope (b) to WLAN interface. When the
address ranges are not defined, MW1122 uses the default values for all
DHCP parameters. The default values are:
D Start address is the interface IP address
D Subnet mask 255.255.255.0
D Range size of up to 253 addresses starting from the interface IP
address.
D DNS address is the interface IP address
D Lease time is 60 minutes
D Domain name is null string
If at least one address range has been defined, then IP address, DNS,
domain name and lease time, if defined, override the default values.
