The Broadband Router
Features Guide
WAN Connectivity
 The first thing you should consider is WAN
connectivity, AKA your Internet connection type. Make sure that the
broadband router selected supports the type of Internet connection you
have. Ethernet connections for cable and DSL modems are the most popular.
Internet WAN Connection
Types
-
RJ-45 Ethernet (cable, dsl,
fiber, starband two-way
sattelite, etc)
-
Serial: Dial-up
analog modem
-
Serial: ISDN
-
USB cable DSL modems are
generally not supported
(with a couple
of exsceptions)
-
One-way cable modems are
not supported
-
One way satellite is not
supported
Cable Modems (two way)
Cable modems can require special configurations if
you have @Home or RoadRunner. @Home requires a 'host name'
setting to be configured in your router. Roadrunner can require that you
type in your original MAC address of your network card into the router
itself (sometimes called spoofing). All modern broadband routers support
these settings.
DSL Modems
Some DSL modems use PPPoE, a special kind
of data transfer protocol to communicate. Most modems support PPPoE very
well. If your DSL provider mentioned anything about 'multi-session' PPPoE
then you may want to look for a multi-session broadband router for added
functionality (this is very rare).
Satellite
Two-Way internet service
This service should work just
fine with any broadband router as long as you have an ETHERNET version of
the satellite modem. Some 2-way sattelite services are USB and
therefore will NOT work with a typical broadband router. Note: Using
a router with a sattelite service may dramatically decrease your broadband
performance. (see http://www.starbandusers.com/
)
Fiber to the home
Some new communities are
offering fiber to the home. This is often a 2-10Mbps connection to the
Internet. Your connection point will be a standard RJ45 ethernet
connection. Any broadband router should work fine.
If you are lucky enough to have a connection over 2Mbps or so, be
sure to look into a fast broadband router. Many routers will
peak around 3Mbps or less.
Serial 56K Dial-up
modem
(POTS or Plain Old
Telephone Service) Some routers have serial ports that support analog
dial-up modems (56k modems). Most often, the use of a dial-up modem on a
router is for Internet connection backup purposes.
Serial ISDN modem
support
Many routers that have
serial ports support ISDN connections. The ISDN connection might be used
as a primary or backup internet connection.
USB Modems
There are
a few rare broadband routers that support specific USB DSL modems. Be
very careful when purchasing a router for your USB modem - it must
specifically support your modem and service.
Connection Bonding or
Teaming
A few rare routers support more
than one broadband connection at once. For some networking applications
the bandwidth of both Internet connections can be utilized. This is an
uncommon practice but it does exist. NexLand supports a connection teaming
technology and Compex supports a parallel broadband technology. See the
reviews here: Nexland

NAT
All broadband routers support
NAT , or network
address translation. This is what allows all your computers to share a
single IP address on the Internet.
If you plan to host many servers through your router
and expose them on the internet, you may want to look into a router with
Multi-NAT functionality. Multi-NAT provides the ability to utilize more
than one IP address on the internet for INCOMMING communications. It does
nothing for outgoing communications. In short, you could run two web
servers on port 80, one on each IP address.
Standard NAT - all outbound and inbound traffic
happens on a single IP address
Multi-NAT - all outbound traffic is on a single ip
address, support for traffic on multiple ip address is supported
