Having issues adding a different Subnet to my TrueNAs

TrueNAS General

Hi,
My Scale server is sitting on 192.168.100.38 and i would like to add the following Subnet 192.168.200.38
I only have 1 10gb nic so would perfer to use this.

I have added an Alias for the new address 192.168.100.38 but still cannot seem to connect or ping it.
But i can ping everything other device on the new subnet.

there are a couple of the new devices on the same switch. they can ping the original address.

I can ping the NAS on the .200 subnet via its ipv6 address. But I can not access NFS using the ipv6 address.
Is there a trick to that as ive not used the ipv6 address before for nfs.

Can anyone please offer any help…

I think you need to be using VLANs as an alias would normally be in the same subnet as the LAN its on

Of course that means you need switches that support VLANs and I sort of assume a router as well - possibly your firewall, assuming its capable

You can of course have multiple IP addresses from different IP networks in the same layer 2 broadcast domain (aka “Ethernet”).

@lawrence_McKay for the system to be reachable the client must have an address in the 192.168.200.x address range/network, too.

The 192.168.200.38 will not be reachable from a client in 192.168.100.x and vice versa. TrueNAS is not a router. If you need that, then follow @NugentS’ advice and it gets a bit more complicated.

You can enable promiscuous mode on the NIC and create a virtual network interface card (NIC) via MACVLAN. Please note that the host NIC and the MACVLAN NIC cannot communicate directly.
