Safari Network User Guide
Safari Network – Internal LAN - Internet via DSL/Cable
router.
The connections for Figure 2-9 are exactly the same
as in Figure 2-8 with respect to the Safari
Network/Router interface. The difference is now we
have added a Local Area Network of users on the
WAN side of the router. As in the previous
configuration (Figure 2-8), the Safari Network belongs
to a private LAN, and is hidden from external network
intrusions via the Internet, or any users on the Internal
LAN if the router is equipped with firewall protection.
Although accessing the Internet from the Safari
Network’s private LAN is allowed, file and resource
sharing are not possible between devices that reside
on the sides of the router. An exception is if the router
has a DMZ port.
