Unable to change static ip address on 3 ports

I’ve managed to change one static ip address out of 4, when ever I try to change any of the other 3 network ports ip address’s I get an error. Any and all help much appreciated.

What part of that error isn’t clear to you? You’re trying to put a second interface on the same network, which isn’t a valid configuration. Either put it on its own network, or just don’t use it at all. See also:

Firstly, welcome to the forum!

The IP you’re trying to set on the interface (10.27.27.94) is overlapping with another network already configured on another interface (10.27.27.0/24).

You can have multiple IP Addresses assigned to a single interface, but not multiple interfaces on the same network (without using LACP).

If you can describe your use-case we can certainly suggest a proper implementation.

I know I am late, but I am new to TrueNas myself. I installed TrueNas Scale last week. I had a similar issue today when adding a second interface. The workaround I found is to leave the DHCP check box checked. DHCP will assign an IP to the new interface(s). Then, go to the router/DHCP server, find the Mac addresses, and reserve the IPs for those interfaces. I hope it helps.


It really doesn’t, because as noted over three months ago, this simply isn’t a valid configuration. The resource linked up-topic explains why.

Thank you all for your responses.

I ended up doing a fresh install which automatically sees and allows all 4 interfaces to be assigned ip address’s.

Kind regards.
