Enabling IP Forwarding on a Port
By default, IP Forwarding is disabled on each router port. Your device will not begin forwarding IP
data packets on any router port until you enable IP Forwarding on that port.
To enable IP Forwarding on a router port, complete the following steps:
1. Use the arrow keys to highlight the IP Forwarding field.
2. Use the ENTER key to toggle the entry to ENABLED.
3. Use the arrow keys to highlight the SAVE command at the bottom of the screen and then press
ENTER. The message “SAVED OK” displays.
Configuring the UDP Broadcast Redirector
In order to locate a server that can provide a particular network service, many IP hosts rely on the
use of LAN broadcasts to send UDP service requests. The UDP port number contained in the
broadcast request packet identifies the service being requested.
Table 23 shows the port numbers
and their corresponding requested services.
