To configure the UDP Broadcast Redirector, complete the following
steps:
1. Use the arrow keys to highlight the UDP Port field under System
Level Setup.
2. ENTER the UDP port number of the UDP service request packets that
you want to redirect (refer to Table 3-1) and press ENTER.
3. Use the arrow keys to highlight the SAVE command field at the
bottom of the screen and then press ENTER. The message "SAVED
OK" displays.
You can enter the UDP port number, or you can use the
NOTE
+REDIRECTOR- option at the bottom of the screen to scroll
through a list of commonly used UDP port numbers. To use the
+REDIRECTOR- option, use the arrow keys to highlight the +
(to go forward), or the - (to go backward), and then press the
ENTER key to scroll in the direction that you select.
The entry for the UDP Port option reflects the UDP port number that is
currently selected. The entry for the UDP Type names the UDP service to
which that port number corresponds.
3.4.10 Enabling Proxy ARP on a Port
By default, Proxy ARP is disabled on all ports, and IP Routing Services
responds only to ARP requests addressed to its own IP address.
In order for one IP host to communicate with another IP host, the target
host's MAC address must be known. In order to learn this MAC address,
the IP host sends an ARP request packet as a LAN broadcast with the
destination IP address of the target IP host. All hosts receive this
broadcast and the one host whose address matches the target IP address
responds with its MAC-layer address. However, because each subnet
constitutes a separate broadcast domain and LAN broadcasts are not
forwarded across routers, ARP does not work beyond a host's local
network or subnetwork. One of the primary purposes of a router is to
confine LAN broadcast traffic to each local network or subnetwork.
