LAN Expansion
Module extends these benefits to topologies that incorporate
multiple LANs.
The following scenarios are examples of situations that
require a Lan Expansion Module:
• You want to manage a single WAN link and your
network includes a firewall/router that splits your
network into two separate LANs: a protected segment
and a DMZ segment.
• You want to manage a single WAN link and your
network includes a router with multiple LAN
segments.
• You have a single WAN link and your network
includes a router with two LANs; one segment may
connect to the LAN through a firewall and the other to
a VPN tunnel management device.
• Your network includes branch offices with two or
three separate LANs that you manage, and only one
WAN link.
