BCM50a Integrated Router Configuration — Basics
session through the LAN interface is an example of traffic destined for the
BCM50a Integrated Router LAN interface itself. You can also use LAN to LAN/
BCM50a Integrated Router rules with IP alias to control routing between two
subnets on the LAN.
WAN to WAN/BCM50a Integrated Router rules apply to packets coming in
through the WAN interface that are destined for either the BCM50a Integrated
Router WAN interface itself or a different subnet on the WAN. A management
session through the WAN interface is an example of traffic destined for the
BCM50a Integrated Router WAN interface itself. By default, the BCM50a
Integrated Router stops WAN computers from using the BCM50a Integrated
Router as a gateway to communicate with other computers on the WAN. You can
configure one of these rules to allow a WAN computer to manage the BCM50a
Integrated Router.
LAN to WAN rules
The default rule for LAN to WAN traffic is that all users on the LAN are allowed
unrestricted access to the WAN. When you configure a LAN to WAN rule, you in
essence want to limit some or all users from accessing certain services on the
WA N.
