Bridge
Provides a wireless side for a specific access point. Enables layer 2 protocols, in which
(usually) one Public IP address is automatically assigned to the subscriber from the cable
company's DHCP servers. In this mode, the first device to connect to a LAN or Wireless
LAN interface gets the Public IP. Hint: Disable the wireless primary network SSID to
ensure that only an Ethernet-based device (e.g., Home Router) gets the Public IP.
NAT
Provides a wireless access point that allows sharing a single Internet connection. Enables
Layer 3 IP protocol, DHCP for private IP address assignment, NAT for network address
and port translation, IP routing, firewall protection, and parental control features. Hint: All
LAN and Wireless LAN interfaces are on the same Private IP subnet, and are translated
to a single Public IP address on the WAN gateway interface to the Internet.
Router
Operates in Router Mode for assigning Static Public IP addresses with RIP when this
mode is enabled. DHCP, Firewall, and NAT functionality are disabled by default. When
Route Mode is enabled, you can configure the device from the Web User Interface (UI)
Routing screen, or through the Telnet Command Line Interface (CLI). Refer to
Using the
Routing Setup Option on page 92
for more information.
NAT Router
Operates in NAT Router mode when enabled. Combines functionality found in both NAT
and Router Modes. You can configure the device from the Web UI Routing screen or
through the Telnet CLI. Refer to
Using the Routing Setup Option on page 92
for more
information.
