Figure 13: Network Deployment with firewalls
Figure 14: Border Controller example configuration
Figure 14 shows how the Border Controller could be configured for the deployment in Figure 13.
The introduction of the firewalls means that there is no longer any direct connectivity between
the Branch and Home offices. All traffic must be routed through the Border Controller. This is
shown by the absence of a link between the Home and Branch subzones.
The Traversal Zone in Figure 14 represents the Enterprise Gatekeeper. The Border Controller
will consume bandwidth from the Traversal Zone for all calls placed to endpoints managed by the
Enterprise Gatekeeper. In this example we have assumed that there is no bottleneck on the link
between the Border Controller and the Enterprise network, so have not placed a pipe on this link.
If you want to limit the amount of traffic flowing through your firewall, you could provision a pipe
on this link.
The traversal subzone in Figure 14 may be used to control the amount of traffic flowing through
the Border Controller itself.
Because the Gatekeeper is only managing endpoints on the LAN, its configuration is simpler as
