So my physical HA computer is multi-homed. One NIC is on my IOT network and the other on a Semi-Trusted network. There is no intervlan routing. It’s been this way for several years and works great.
HA is also configured to connect to a SMB share on my NAS (on a Secured network) via very specific source/destination firewall rules. What I’m noticing recently is that sometimes HA is using the IOT NIC and other times the Semi-Trusted NIC when trying to reach my NAS… I had to configure both source IP address in my Firewall rules which I didn’t have to do until fairly recently.
HA seems to be ignoring the NIC I have marked as “default”.
Segmented networks are not officially supported within HA.
HA is designed and expects a flat subnet to work as intended.
This is because every segmented network is different for IP’s and number of segments and firewalls and sharing rules and about 650495849085 other things.
This does not mean you can’t use them or that they can’t be made to work, it means that to get them working you are the support structure on your own subnet(s). Consider it Advanced mode.
Fair enough… Updating my firewall rule was easy enough and everything works like a charm… just thought it was odd that HA lets you configure a “default” NIC but it wasn’t operating as I was thinking it would.
