Figure 6.202 Advanced Routing Properties<br />

You can configure the following settings:<br />

Routing Mode Select one of the following routing modes:<br />

Route Use route mode if you want your gateway to function as a router between two networks.<br />

NAPT Network Address and Port Translation (NAPT) refers to network address translation<br />

involving the mapping of port numbers, allowing multiple machines to share a single IP address.<br />

Use NAPT if your LAN encompasses multiple devices, a topology that necessitates port<br />

translation in addition to address translation.<br />

Device Metric The device metric is a value used by the gateway to determine whether one route<br />

is superior to another, considering parameters such as bandwidth, delay, and more.<br />

Default Route Select this check box to define this device as a the default route.<br />

Multicast – IGMP Proxy Internal / Default <strong>iPECS</strong> <strong>SBG</strong>-<strong>1000</strong> serves as an IGMP proxy, issuing<br />

IGMP host messages on behalf of its LAN hosts. This check box is enabled on LAN connections<br />

by default, meaning that if a LAN multicast server is available, other LAN hosts asking to join<br />

multicast groups (by sending IGMP requests) will be able to join its multicast group. However, this<br />

check box is disabled on the WAN connection by default, meaning that LAN hosts will not be able<br />

to join multicast groups of WAN multicast servers. When creating a WAN-LAN bridge, this check<br />

box must also be deselected.<br />

IGMP Query Version <strong>iPECS</strong> <strong>SBG</strong>-<strong>1000</strong> supports all three versions of IGMP. Select the<br />

version you would like to use. Note that this drop-down menu appears for LAN connections only.<br />

Routing Information Protocol (RIP) Select this check box to enable the Routing Information<br />

Protocol (RIP). RIP determines a route based on the smallest hop count between source and<br />

destination. When RIP is enabled, you can configure the following:<br />

• Listen to RIP messages—select either ‘None’, ‘RIPv1’, ‘RIPv2’ or ‘RIPv1/2’.<br />

• Send RIP messages—select either ‘None’, ‘RIPv1’, ‘RIPv2-broadcast’ or ‘RIPv2-multicast’.<br />
