Bridging

Some times it is necessary to bridge a network. This occurs because the network to be monitored has devices that the end customer does not want to assign ip address or or add to internal dns. When bridging occurs, a single ip address is provided that can be static or dhcp.

This allows a previously private network to be monitored by the addition of a Hardware Agent and a Router

Corporate LAN

This is the backbone of the end customer. It is usually in the 10.x.x.x ip scheme

Private LAN

This is a standalone network which may or may not have access to the corporate network and WAN. It is usually in the address space of 192.162 or 172.16 address space.
