MW1122 User Manual
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 13, scope (a) is 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:
DStart address is the interface IP address
DSubnet mask 255.255.255.0
DRange size of up to 253 addresses starting from the interface IP address.
DDNS address is the interface IP address
DLease time is 60 minutes
DDomain 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.
