CONFIGURING ADVANCED IP ROUTING

OVERVIEW

By default, IP routing is disabled when you first install your system software. After IP routing is enabled, there are optional advanced features available. Optional advanced IP routing features include:

•Static ARP Table Entries

ARP (Address Resolution Protocol) is used to translate IP addresses to Ethernet addresses. As a rule, this translation is handled dynamically. In rare situations, a user may need to manually enter this translation. This menu item allows you enter a static ARP table entry manually.

•Enable/Disable Isolated Mode Option

The Isolated mode option helps to restrict the resources to which remote IP devices can get access.

•Static Routes Lookup via RADIUS

The Static Routes Lookup via Radius option allows you to either enable or disable maintaining static routes for devices on the RADIUS Server. This option is only applicable when a RADIUS Server is in use.

•IP Address Pool

The IP Address Pool allows you to configure a list of IP addresses that can be dynamically assigned to remote IP devices as they connect to the system.

•IP Filters

IP Filters allow you to control the admission and transmission of individual IP datagrams based on the datagram’s contents.

•DHCP

Dynamic Host Configuration Protocol (DHCP) allows you to access the DHCP server to allocate IP addresses to all types of remote IP devices.

•Security Associations

If you have purchased the CyberSWITCH encryption option, you will need to configure a set of Security Associations in order to use IP layer encryption. These associations include the IP addresses of datagrams that you select to be encrypted.

•NBNS and DNS Name Server Addresses

This feature allows you to assign IP addresses to Domain Name System (DNS) or NetBIOS Name Servers (NBNS).

This chapter includes a section for each advanced IP routing feature.
