3.1.2 LOCAL PORT
Configure your gateway’s IP address of the local port here. It has to be a
private IP address such as (10.x.x.x, 192.x.x.x are reserved for LAN use).
Subnet Mask. The subnet mask determines how many computers are allowed
in this network. A class C network with the subnet mask 255.255.255.0 allows
maximum 253 users (254-1, because gateway got one already) in your local
area network. Usually a class C network is satisfactory for your local network.
To enable the DHCP server of the gateway, please click the check box.
Start IP address. Specify the start of the IP address you want to assign to
DHCP users. The default value is 192.168.1.2. (Please make sure there is no
fixed IP address within your DHCP assignation range on the LAN, otherwise
your DHCP client cannot get the IP address correctly.)
Number of IP address. Assign the number of users allowed to use the DHCP
service. The default value is 128 users.
Lease Time. A DHCP user’s PC gets an IP address with a lease time, when
the lease time is up the IP address assigned to that user’s PC will be expired.
The user’s PC must connect to the DHCP server again to get a new IP address.
