Ctrld not responding to queries from different subnet IPs

[xduknet]

Despite having the CIDRs setup with networks defined, no matter what I do with the Windows service version, the queries from routed subnets do not appear to get a response from the daemon. It's not a firewall issue because the gateway is routing okay and tracerouting is fine. Device communication between other devices across the different subnets also works fine. ICMP responds to pings.

What seems to be happening is that the CTRLD service just ignores everything that isn't already a subnet of it's local addresses - so just having physical network adapters, each within the correct subnet works as expected even if the listener is actually only setup on one. I was under the impression that as long as one of the CIDRs exist in the network rules groups (and restricted is not set to true) it should listen to any incoming IPs.

The CTRLD service is running within a Virtualbox instance. I'm at a bit of a loss because there's no debug information to see if the listener even sees the request.

What's network mode did you run for your Virtualbox?

The system is running in Bridged mode fully promiscuous. It looks like a host issue on the VM where it does filtering of packets coming from subnets not allocated to a network card on the host. It is working ok by creating several network adapters for each subnet. I need to do further digging as the problem does not appear to be directly associated with the CTRLD daemon.
