Hi All,
Bit of background on what I'm doing:
I've got Home Assistant all up and running and working lovely, I want to provide the kids with their own dashboards.
I have a separate network/vlan called SmartNet for any IOT related devices and Home Assistant sits in this network as well.
I have a network/vlan called ClientNet which myself and my partner are within and any of our devices etc
I have a network/vlan called KidsNet which the kids use this as it's more locked down and has it's own Pi-Hole DNS etc.
There are more networks/vlans but don't think they're all relevant.
I've a few rules setup where the kids can access two Chromecasts in the SmartNet network and Plex within a network called ServerNet and then a block rule that blocks all other network access.
All this works perfectly and as expected.
Over the weekend I added a rule to allow access to Home Assistant and was unable to access this from the KidsNet, if I allowed access to other web based devices the rule worked as expected.
If I disable the network block rule from the KidsNet I am able to access everything within SmartNet apart from Home Assistant.
As part of my tests I tried to ping Home Assistant from Opnsense and every interface apart from KidsNet was able to ping the Home Assistant device.
Lastly I also have Opnsense setup in HA and the same happens on the slave instance as well.
I am well and truly out of ideas so any input would be welcomed.
Thanks,
Nick
