Lan-To-Lan Application - D-Link DI-300 series User Manual

substitute the higher order 0s with the dot decimal of the additional
subnet bits. For instance, to partition your class C network
204.247.203.0 with subnet mask 255.255.255.0 into 16 subnets (4
bits), the new subnet mask becomes 255.255.255.240.

LAN-to-LAN Application

A typical LAN-to-LAN application is to use the DI-300 or
DI-300M to call from a branch office to the headquarters, as
depicted in the following diagram.
For the branch office, you need to configure a Remote Node in
order to dial out to the headquarters. Additionally, you may also
need to configure Static Routes if some services reside beyond the
immediate remote LAN.
