UDP Broadcast Relay
Certain vendors use broadcasts to identify their equipment within one ethernet segment. Unfortunately if you split your network with multiple VLANs you loose the ability of identifying your equipment.
This is where “UDP broadcast relay” comes into play! It will forward received broadcasts to other configured networks.
Every UDP port which will be forward requires one unique ID. Currently we support 99 IDs!
A description can be added for each and every unique relay ID. This is useful to distinguish between multiple different ports/appliactions.
The interface used to receive and relay individual broadcast packets. If you want to receive/relay packets on both eth1 and eth2 both interfaces need to be added.
Set the source IP of forwarded packets, otherwise original senders address is used.
The UDP port number used by your apllication. It is mandatory for this kind of operation.
Each broadcast relay instance can be individually disabled without deleting the configured node by using the following command:
In addition you can also disable the whole service without the need to remove it from the current configuration.
You can run the UDP broadcast relay service on multiple routers connected to a subnet. There is NO UDP broadcast relay packet storm!
To forward all broadcast packets received on UDP port 1900 on eth3, eth4 or eth5 to all other interfaces in this configuration.
