ROUTER > IP > UDP RELAY
Write security: 2; Read security: 2
Allows the router to act as a relay agent for UDP (User Datagram Protocol) broadcast packets. Normally, a
router will not forward UDP broadcast packets. However, many network applications use UDP broadcasts
to configure addresses, host names, and other information. If hosts using these protocols are not on the
same network segment as the servers providing the information, the client programs will not receive a
response without enabling the UDP relay agent.
ROUTER > IP > UDP RELAY > ENABLE
Write security: 2; Read security: 2
Enables/disables the router to act as a relay agent.
ROUTER > IP > UDP RELAY > RELAY TABLE
Write security: 2; Read security: 2
(Available only when UDP Relay is ENABLED.) Lists up to four relay destination servers (RELAY TABLE
0-3). Each server can be configured using the following menus: ENABLE, IP, and UDP.
ENABLE
Write security: 2; Read security: 2
Enables/disables this field. Select either STANDARD or SPECIFIED. (DISABLE is not used.)
STANDARD
(DEFAULT)
Relays any of the following standard UDP protocols: DHCP, TFTP,
DNS, NTP (Network Time Protocol, port 123), NBNS (NetBIOS Name
Server, port 137), NBDG (Net BIOS Datagram, port 138), and BootP.
SPECIFIED Specifies the UDP port (1 to 65,535) in the UDP Port columns
(maximum of three per server).
IP
Write security: 2; Read security: 2
Defines the IP address of the server that receives the relay packet.
UDP PORTS 1 - 3
Write security: 2; Read security: 2
Specifies the UDP ports to relay. These fields are active only when ENABLE is set to SPECIFIED.
