Mike,

I’m scratching my head how it is possible that Your system has IPv6 interface?
Looking on /boot/cmdline.txt in vanilla image:

root=/dev/mmcblk0p2 rw rootwait console=ttyAMA0,115200 console=tty1 selinux=0 plymouth.enable=0 smsc95xx.turbo_mode=N dwc_otg.lpm_enable=0 kgdboc=ttyAMA0,115200 elevator=noop ipv6.disable=1

look at end of line: how You can have IPv6 interface with ipv6.disable=1?

vanilla image has following interfaces in my case:

eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.1.159  netmask 255.255.255.0  broadcast 192.168.1.255
        ether b8:27:eb:2f:4b:fc  txqueuelen 1000  (Ethernet)
        RX packets 16225404  bytes 1678337378 (1.5 GiB)
        RX errors 0  dropped 214  overruns 0  frame 0
        TX packets 4102218  bytes 424668576 (404.9 MiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536
        inet 127.0.0.1  netmask 255.0.0.0
        loop  txqueuelen 1  (Local Loopback)
        RX packets 37  bytes 15267 (14.9 KiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 37  bytes 15267 (14.9 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

as You see there is no IPv6.

how You then are getting IPv6 interface on my SD image?


Nevertheless issue with Your setup where You have: FE IPv6/IPv4 + BE only IPv4 shouldn’t break BE discovery.
This IMHO should be investigated (and probably reported as myth bug)

I think it will be good to do some tests in Your case:
1.disable IPv6 on FE and see how discovery goes
2.enable IPv6 on BE see how discovery goes
