• DHCP - Dynamic Host Configuration Protocol (DHCP)
automatically issues IP addresses within a specified
range to devices on a network. This is a common option
when you connect through a cable modem.
• PPPoE (PPP over Ethernet) - A network protocol for
encapsulating Point-to-Point Protocol (PPP) frames
inside Ethernet frames. It is used mainly with DSL
services where individual users connect to the DSL
modem over Ethernet and in plain Metro Ethernet
networks.
• PPTP - The Point-to-Point Tunneling Protocol (PPTP) is
a method for implementing virtual private networks.
PPTP uses a control channel over TCP and a GRE
tunnel operating to encapsulate PPP packets.
• L2TP - Layer 2 Tunneling Protocol (L2TP) is a tunneling
protocol used to support virtual private networks
(VPNs). It does not provide any encryption or
confidentiality by itself. It relies on an encryption
protocol that it passes within the tunnel to provide
privacy.
• Cellular Modem - Connect to the Internet using a
wireless modem to a cellular ISP through the USB port.
• Analog Modem - Connect to the Internet using an
analog modem through a USB port. In the WebUI
application, you can configure to use an analog modem
through the serial port.
• Bridge - Connects multiple network segments at the
data link layer (Layer 2).
• Wireless - Connects to a wireless network. Connection
through the wireless interface in the First Time
Configuration Wizard is always DHCP.
