udpbroadcastrelay is a UDP multicast relayer. Its intended use is to
|
|
rebroadbcast udp packets on a specific port across interfaces, be those
|
|
interfaces physical or VLAN.
|
|
|
|
It is used where devices such as Sonos or Sky are spread accross
|
|
different subnets and are not able to detect the servers or devices.
|
|
|
|
Examples of different devices and the ports are as follows:
|
|
|
|
Syncthing discovery
|
|
udp_vars="--id 1 --port 21027 --dev igb1 --dev igb2"
|
|
|
|
mDNS / Broadcast DNS (Chromecast Discovery + Bonjour + More)
|
|
udp_vars="--id 1 --port 5353 --dev eth0 --dev eth1 --multicast 224.0.0.251 -s 1.1.1.1"
|
|
|
|
(Chromecast requires broadcasts to originate from an address on its subnet) use
|
|
the rebroadbcast address option.
|
|
|
|
SSDP (Sonos Roku Discovery + More)
|
|
udp_vars="--id 1 --port 1900 --dev eth0 --dev eth1 --multicast 239.255.255.250"
|
|
|
|
Lifx Bulb Discovery
|
|
udp_vars=" --id 1 --port 56700 --dev eth0 --dev eth1"
|
|
|
|
Broadlink IR Emitter Discovery
|
|
udp_vars=" --id 1 --port 80 --dev eth0 --dev eth1"
|
|
|
|
Warcraft 3 Server Discovery
|
|
udp_vars=" --id 1 --port 6112 --dev eth0 --dev eth1"
|
|
|
|
It is a requirement that generally a firewall entry will be required to allow the server responses
|
|
back to the requesting client. As it's not known what the port/address of the server is then this
|
|
entry will need to be created manually.
