Routing

You can choose to setup your gateway to use static or dynamic routing. Dynamic routing automatically adjusts how packets travel on the network, whereas static routing specifies a fixed routing path to neighboring destinations.

Routing

Select 'Advanced' or 'Basic' routing.

Routing Mode

Select one of the following Routing modes:

Route

Use route mode if you want your gateway to function as a router between two networks.

NAPT

Network Address and Port Translation (NAPT) refers to network address translation involving the mapping of port numbers, allowing multiple machines to share a single IP address. Use NAPT if your LAN encompasses multiple 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 bandwidth, delay, and more.

Default Route

Select this check box to define this device as a the default route.

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 following:

• Listen to RIP messages - select 'None', 'RIPv1', 'RIPv2' or 'RIPv1/2'.
• Send RIP messages - select 'None', 'RIPv1', 'RIPv2-broadcast' or 'RIPv2-multicast'.

Multicast - IGMP Proxy Internal

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 'Multicast IGMP Proxy Internal' check-box to enable this feature.

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.
