What is a Local Area Network (LAN)?
Local Area Networks are a group of computers and other devices that
cover a small local area, like a home, office or small group of
buildings. They share
information and resources.
Home networks often link PCs, laptops,
printers, DSL or cable modems, video games systems, and digital video
recorders.

What is a router and do I need
one?
A router is a network device that connects to your DSL or cable
modem allowing many people to access the internet on different computers
at the same time. It acts as
a gateway between the internet and all of the computers in your home
network (LAN). Nextera offers
a Phone Adapter/Router if you don’t already have one. If
purchasing a router, it must:
- Be DSL/cable modem web
safe
- Provide Network Address Translation
(NAT)
- Provide Dynamic Host Configuration Protocol
(DHCP)
Most routers support these requirements.

Does my router work with Nextera
service?
Nextera service will work with most routers. If you are having trouble with
Nextera service on an older router, we recommend that you download and
install the router’s latest firmware from the manufacturer’s site. Both NAT (Network Access
Translation) and DHCP (Dynamic Host Configuration Protocol) must be
enabled on your router. If you are using DSL, your router
should be configured for PPPoE.

Can I subscribe to Nextera and use my
existing networking equipment?
Nextera works with existing home networks or LANs that support NAT
and DHCP. DHCP is used to
assign dynamic IP addresses to devices on your network. NAT converts IP address in one
network to a known but different IP address in another
network.

What ports do I need open if my Phone
Adapter is behind a firewall?
No ports need to be open if you have a simple NAT router. Most Nextera customers simply
connect their phone adapter to the router and it works. If you have a firewall, you must
give the Phone Adapter rights to access certain internet ports
including 69, 5060-5063, 10000-20000 and the range
of 28000-28020.
