25.04.: adding vlan doesnt work

TrueNAS General

Hi guys

I just successfully upgraded my system to TrueNAS SCALE 25.04 (via 23.x and 24.04.x). Now I’m in the process of reinstalling my apps.

My Goal: I want to assign dedicated IP addresses to my apps (e.g., Grafana) like 192.168.1.51.

My Problem: Every network change I attempt fails during the “Test Changes” step and gets reverted.

What I’ve tried so far:

  1. VLAN Attempt: I followed the Lawrence Systems guide (https://youtu.be/P6WrEp64qzg) to create a VLAN for the apps. As soon as I configure the new VLAN interface and click “Test Changes,” the changes are reverted after 60 seconds.

  2. Attempt to Switch to Static IP: I also tried to disable DHCP on my main network interface. However, when I edit the interface, uncheck “DHCP,” and then click “Test Changes,” this also fails and reverts.

My Network Configuration:

  • Router: pfSense

  • TrueNAS IP: 192.168.1.10 (currently assigned via DHCP reservation from pfSense)

  • Gateway: 192.168.1.1

  • Desired App IP: 192.168.1.51

What is the correct procedure to switch from a “DHCP reservation” to a “Static IP + Alias” without the “Test Changes” step failing?

Thanks for your help!

My router ip is configured in the global configuration correctly, i think
