When I assign a static IP in TrueNAS on my second NIC it works fine during the 60 seconds when the interface is being tested, but after the test is done the IP settings gets wiped. The first NIC remain fine.
I’m running TrueNAS 25.10.2.1 on Promox 9.1.7. In Proxmox I have two network interfaces 2.5gbps and 10gbps. Both are set up with Linux bridges 2.5g with HDCP and 10g no IP in Proxmox. Can’t see that I’m doing anything wrong. Could this be a bug in TrueNAS?
After clicking on “Test” you need to connect to the UI again and “Save” to persist your changes. It’s a two step process, so users do not accidentally lock out themselves.
I’ve found the problem. When setting the second NIC to static IP, the first NIC will automatically be set to static IP as well with no IP address. Then when selecting “test” TrueNAS it will log the user out and when logging back in all settings has been reverted and no save button will appear.
This time I also edited the first NIC and set it back to DHCP after editing the second NIC and this time the save button appeared and everything seems to work fine.
I would say this is a bug. If you edit one NIC you don’t expect it to change another NIC.
Are you trying to configure both of your NICs for the same network/prefix? This is not supported.
enp6s18 - DHCP (192.168.1.30/24) - connected to my main network
enp6s19 - Static IP 192.168.10.1/24 - DAC to another computer
Looks good and should work.
