Hey all,
Thanks for the replies and sorry for the late response.
I managed to get the rules to work by clearing the states, enabling the rules and clearing the states again. It seems to be iffy and didn't always work when I disabled and re-enabled so I'm going to blame this on the old v2.0.1 which I will soon upgrade.
Anyhow, I only needed the rule for a few minutes to test an alert from our monitoring system which specifically required me to leave the device online but only cut communication between the two specific device. The test is done so no further need to investigate.
Thank you all.
