Chapter 1: Getting started
■
Avoid providing web or file-sharing services over your telephony modem. Besides certain
vulnerability problems, most cable companies prohibit running servers on consumer-
level accounts and may suspend your account for violating your terms of service.
■
Use the service provider's mail servers for sending email.
■
Avoid using proxy software unless you are certain that it is not open for abuse by other
Internet users (some are shipped open by default). Criminals can take advantage of open
proxies to hide their identity when breaking into other computers or sending spam. If
you have an open proxy, your service provider may suspend your account to protect the
rest of the network.
Ethernet connection
Ethernet is a standard method of connecting two or more computers into a Local Area
Network (LAN). You can use the Ethernet connection if your computer has built-in Ethernet
hardware.
Your telephony modem package does not include an Ethernet cable (the connectors look like
wide telephone connectors); you can purchase this cable, if necessary at a computer retailer.
If you are connecting your telephony modem directly to a computer or to a wireless router
(with the Ethernet connection from your telephony modem connected to the WAN input on
the router), ask for Category 5e (CAT5e) straight-through cable. CAT5e cable is required for
gigabit Ethernet (Gig-E), not regular CAT5 cable.
