1.
DHCP Server:
Choose DHCP Server to
Enable
. If you enable the DHCP
Server function, this gateway will assign IP address to LAN computers or
devices through DHCP protocol. This device provides up to 4 DHCP servers
to serve the DHCP requests from different VLANs.
2.
LAN IP Address
: Specify the local IP address of the enabled DHCP Server.
It’s the LAN IP address of this gateway for DHCP-1 server. Normally, this IP
address will be also the default gateway of local computers and devices.
3.
Subnet Mask:
Select the subnet mask for the specific DHCP-n server.
Subnet Mask defines how many clients are allowed in one network or subnet.
The default subnet mask is 255.255.255.0/24, and it means maximum 254 IP
addresses are allowed in this subnet. However, one of them is occupied by
LAN IP address of this gateway, so there are maximum 253 clients allowed in
LAN network. Hereafter are the available options for subnet mask.
