Actiontec Broadband Router User Manual
• NAPT - Select this option to activate NAPT (Network Address and Port
Translation), which refers to network address translation involving the
mapping of port numbers and allows multiple machines to share a single IP
address. Use NAPT if the local network contains multiple devices, a topol-
ogy that necessitates port translation in addition to address translation.
Device Metric The device metric is a value used by the Router to determine
whether one route is superior to another, considering parameters such as band-
width, delay, and more.
Default Route Click in this check box to define the connection as the
default route.
Multicast - IGMP Proxy Default Click in this check box to enable the Router to

the routing of multicast packets according to the IGMP requests of local network
devices asking to join multicast groups.
