tiple devices, a topology that necessitates port translation in addition to address
translation.
Device Metric The device metric is a value used by the gateway to determine
whether one route is superior to another, considering parameters such as band-
width, delay, and more.
Default Route Select this check box to define this device as a the default
route.
Multicast – IGMP Proxy Default IGMP proxy enables the system to issue IGMP
host messages on behalf of hosts that the system discovered through standard
IGMP interfaces. IGMP proxy enables the routing of multicast packets according to
the IGMP requests of LAN devices asking to join multicast groups. Select the 'Mul-
ticast IGMP Proxy Default' check box to enable this feature.
Routing Information Protocol (RIP) Select this check box to enable the
Routing Information Protocol (RIP). RIP determines a route based on the smallest
hop count between source and destination. When RIP is enabled, select the follow-
ing:
 Listen to RIP messages—select 'None', 'RIPv1', 'RIPv2' or 'RIPv1/2'.
 Send RIP messages—select 'None', 'RIPv1', 'RIPv2-broadcast' or 'RIPv2-
multicast'.
Routing Table Allows you to add or modify routes when this device is active.
Use the 'New Route' button to add a route or edit existing routes.

9.4.12.6 PPP
Point-to-Point Protocol (PPP) is the most popular method for transporting packets
between the user and the Internet service provider. PPP supports authentication
protocols such as PAP and CHAP, as well as other compression and encryption
protocols.
PPP-on-Demand Use PPP on demand to initiate the point-to-point protocol ses-
sion only when packets are actually sent over the Internet.
