Configuring the IP Helper Features

The IP Helper feature provides the ability for a router to forward configured UDP broadcast packets to a

particular IP address. This allows applications to reach servers on non-local subnets. This is possible even when

the application is designed to assume a server is always on a local subnet or when the application uses

broadcast packets to reach the server (with the limited broadcast address 255.255.255.255, or a network

directed broadcast address).

You can configure relay entries globally and on routing interfaces. Each relay entry maps an ingress interface

and destination UDP port number to a single IPv4 address (the helper address). Multiple relay entries may be

configured for the same interface and UDP port, in which case the relay agent relays matching packets to each

server address. Interface configuration takes priority over global configuration. If the destination UDP port for

a packet matches any entry on the ingress interface, the packet is handled according to the interface

configuration. If the packet does not match any entry on the ingress interface, the packet is handled according

to the global IP helper configuration.

IP Helper Global Configuration

Use the IP Helper Global Configuration page to globally enable the IP Helper admin mode and to configure

global relay settings on the switch.

To display the page, click LAN > L3 Features >IP Helper > Global Configuration in the navigation tree.
