Managing Connectivity Between Your Home Devices and the Internet
You home network accesses the Internet through your security network router
DMZ
. The router’s
DMZ selectively exposes your home network to the Internet.
By default, your home network can access the Internet, but entities in the Internet cannot access
computers and devices in your home network. This can be a problem for certain types of computing
and also for using entertainment systems to watch movies, play games, etc.
Figure 4: Security Network Router Blocks Access to Your Home Network from the Internet
(Default)
You can choose to have your security network router expose your home network to devices in the
Internet (see Figure 5).This will not change your security network’s protection from outside entities.
If your home network is exposed to Internet entities, you can choose to hide it (see page 47).
