HDHomeRun any successful cases accross vlans?

[FullyBorked]

Been banging my head on the desk trying to solve this to no resolve. I have an HDHomeRun box in a seperate IoT vlan.  I've installad the udp broadcast relay plugin.  I have a floating firewall rule for UDP port 65001 for IoT and LAN networks and see allowed packets in the log. 

UDP Broacast relay config -

Port: 65001
Relay interface: IoT/LAN
Broadcast address: I've tried all kinds of combos even blank. I see traffic on 255.255.255.255 but I guess I can't use that in the plugin as it fails to start with that.  So what can I should I use here?
Source address: 1.1.1.1

Not sure how to troubleshoot this, I see allowed traffic, I see a single UDP 65001 packet from my computer, then two (return?) packets from the HDHomeRun box both UDP 65001.  But the app seems to not see the traffic. 

I welcome any help getting this figured out if it's possible.

On UDPBroadcastRelay, leave the source and broadcast blank in your config. Set port as 65001.

Create a floating firewall rule and set the following:

Interfaces: select the same interfaces you put in the UDPBR config.
Protocol: UDP
Source: IP of HDR
Source Port: 65001
Dest: Net option for the network your device running the app is on.  Mine was LAN Net.

Good luck.
