So, like many folk who like to segregate our SOHO home networks with VLANs, subnets, etc., I was frustrated at not being able to use iOS apps, Windows drivers etc. to find and use (in my case) a Play-Fi LAN streaming speaker system on my logical networks.

First, I was able to use IGMP-PROXY for the standard broadcast protocols across my VLANs, however, although systems (NAS, Printers, etc.) were happily broadcasting, the Phorus/Play-Fi 255.255.255.255:10102 broadcasts weren't reflected across the VLANs, which is actually a good thing in general, but not for my use case.

Here is my LAN equipment configuration:

ERL3 -> ToughSwitch 8-Pro (root switch) -> Cisco SG 200-08

Definitive Technology W9 WiFi/Wired speaker is on my home user network VLAN 5 and is located in my den

Office network is VLAN 6

In order to have devices on VLAN 6 discover and use the W9 on VLAN 5, I needed to rebroadcast 255.255.255.255 on port 10102. I accomplished this, by downloading and compiling Joachim Breitner's brilliant udp-broadcast-relay on my ERL3 and then integrating it into the CLI configuration.

YMMV and of course, there is always a risk using any non Ubiquiti approved/test software, but for those of us stuck with equipment that forces a home user paradigm on our networking, this may be the antidote.

• upload install_ubnt_bcast_relay.v1.2 to your router

    curl -Lo /tmp/install_ubnt_bcast_relay.v1.2.tgz https://github.com/britannic/ubnt-bcast-relay/raw/master/install_ubnt_bcast_relay.v1.2.tgz 
    cd /tmp
    sudo tar zxvf ./install_ubnt_bcast_relay.v1.2.tgz
    sudo bash ./install_ubnt_bcast_relay.v1.2
    select menu option #1 if installing for the first time
    select menu option #2 to completely remove ubnt_bcast_relay
  

• upload ubnt-bcast-relay_ER-X.tgz to your router and run the installer

    curl -Lo /tmp/ubnt-bcast-relay_ER-X.tgz https://github.com/britannic/ubnt-bcast-relay/raw/master/ubnt-bcast-relay_ER-X.tgz
    cd /tmp
    sudo tar zxvf ./ubnt-bcast-relay_ER-X.tgz
    sudo bash ./ubnt-bcast-relay/install.sh
  

Using the network description above, here is a working example:

Run configure:

set service bcast-relay id 1 description 'Play-Fi listener'
set service bcast-relay id 1 interface eth0.5
set service bcast-relay id 1 interface eth0.6
set service bcast-relay id 1 port 10102
commit
save
exit

This generates a configuration stanza like this:

service {
    bcast-relay {
        id 1 {
            description "Play-Fi listener"
            interface eth0.5
            interface eth0.6
            port 10102
        }
    }
}

Run configure delete service bcast-relay commit save exit
