SOLVED All network interfaces disabled when I try to set one to static IP

[tyler72us]

My NAS has 4 network interfaces. 2 are used with a VM, 1 is my main LAN interface, and the last one is open. I am trying to set up a direct connection between my homelab and my TrueNas using the last interface. (both are 2.5 Gbps, where as my switch is only 1 Gbps). When I go into the try set the static IP using https://www.truenas.com/docs/scale/scaletutorials/network/interfaces/settingupstaticips/ after I click save, but before clicking test it disables all my interfaces. This makes the test fail becuase the gui interface is disabled, but it isn't even the one I'm trying to change. I'm not sure how to work around this. I've tried it using a keyboard and monitor as well with the same results, so it must be something I'm missing right?

Did you stop all apps and VMs before making the changes? (you need to do that)

I didn't the first time, but I have now tried that with the same results.

I am trying to set up a direct connection between my homelab and my TrueNas using the last interface.

What is your homelab? A switch to your homelab? Another machine?

Does this machine / homelab also have a NIC configured on the 10.0.0.1 subnet?

This makes the test fail becuase the gui interface is disabled, but it isn't even the one I'm trying to change.

Did you remove all IPV6 entries on the other interfaces during setup of the static IP?

As far as I know the test does neither fail nor succeed, it may just be that you lose your network connectivity. Do you mean that and it reverts back after 60s?

Some comments:

• If your existing NIC is using DHCP, you CAN'T add another, (as far as I know). Change it to static first.
• You can't have 2 IPs in the same sub-net. Make a new sub-net for the 2nd NIC's IP.

Resource - Multiple network interfaces on a single subnet

We've had a number of people over the years bring up the topic of multiple network interfaces on a single subnet. Often done by Windows administrators or storage admins, where it works to varying degrees, this is sadly not proper IP networking...

I had to disable DHCP and set a static IP (the same it already had) for my main interface first. I would not have guessed that. I already had a static IP on my router so I didn't think there would be an issue. Thank you!

Great. If the problem is solved, you can change the first post's title modifier to solved.
