The UDP RELAY TABLE menu
Standard IPV4 router operation does not allow for the forwarding of subnet broadcasts. However certain
network applications rely on the relay of UDP packets sent to the subnet broadcast address. For example
Windows browsing service relies on Netbios datagram service packets (addressed to UDP port 138 and
the IP subnet broadcast address) reaching all stations within the browsing domain. The UDPGw
configuration must be turned to “On” for each port that we wish the relay operation to work on and an
entry in the UDP relay table must be added for each service that must be relayed. Some well-known
service types are pre-configured for addition to this table – other services require the appropriate UDP
port number to be configured. The example below shows the configuration required to get legacy
