TrueNAS Scale UI refreshes every seconds after adding VLAN

No. I ping when im at home using local connection, from each VM that are on the VLAN.

I found a post on forum that looks like they got the same problem but it’s not solved yet.
And also i found a post on reddit that i think similar to my problem also. I tried to add the Outbound rule as the comment suggested but still no luck. I use opnsense as my firewall/router, I think i forgot to mention that if that’s an important info.
