Multiple Networks - ZyXEL Communications PLA6456 User Manual

Alternatively, use the Web Configurator to set up security on the PLA. Although the PLA is a "plug-and-
play" network expanding solution there are several reasons for enabling security on the HomeGrid
network in your home.
It is easy and only requires you to change a network name.
1
It is a good idea to ensure privacy of your communication. When you use the PLA and other PLAs, the
2
electrical wiring in your home becomes an extension of your Ethernet network. Your network traffic flows
freely within the electrical circuit of your home and is bounded in most cases by a power meter.
Without security (encryption) your information is accessible to anyone using a PLA on the same
electrical circuit. In some cases, a circuit can be shared by more than one household.
To prevent compromising your network security, you can create a private network. A private network
uses a Domain Name to make sure that only permitted PLAs can communicate in your network. See
Section 3.4 on page 19
You may need to change the Domain Name to create multiple HomeGrid networks. See the next
3
section for more information on how to set up a multiple network.

1.7 Multiple Networks

Multiple HomeGrid networks can coexist on a single Powerline circuit. You might want to implement
multiple HomeGrid networks in a small office environment where you have two separate Ethernet
networks.
Connect one PLA to a router or switch on the first Ethernet network and assign a Domain Name (for
1
example "HomeGrid") to this PLA (see
PLAs to your network by plugging them into your Powerline outlets and assigning them "HomeGrid". This
completes the configuration of your first HomeGrid network.
Connect another PLA to a router or switch on the second Ethernet network and assign a different
2
Domain Name (for example "HomeGrid2") to this PLA. Again, add additional PLAs and assign them
"HomeGrid2".
You now have two private networks on your Powerline circuit. Information is not shared between the
two networks as only PLAs with the same Domain Name can communicate with each other.
