[Help] SMB server with multiple NICs

TrueNAS General

I have set up a TrueNAS SCALE with 2 NICs on it. I would like to segregate clients SMB access between the 2 NICs.

Here is the BIND record of the IPs belongs to the machine:

truenas.lan.home.	IN	A	10.77.0.91
truenas2.lan.home.	IN	A	10.77.0.92

And the SMB share settings:

  • NetBIOS Name: truenas
  • NetBIOS Alias:
  • Workgroup: WORKGROUP
  • Description: TrueNAS Server

However, I discovered the clients always connect to the 10.77.0.91 despite the file
/etc/fstab listed truenas2.lan.home or 10.77.0.92 as the host such as following:

//truenas2.lan.home/foo /mnt/truenas/foo cifs rw,vers=3.0,auto,credentials=/root/.truenas_credentials,uid=1097,gid=1097,file_mode=0664,dir_mode=0775,noserverino 0 0
//10.77.0.92/bar /mnt/truenas/bar cifs rw,vers=3.0,auto,credentials=/root/.truenas_credentials,uid=1097,gid=1097,file_mode=0664,dir_mode=0775,noserverino 0 0

TrueNAS version: TrueNAS-SCALE-23.10.2

How to make clients connect to 10.77.0.92?

Thank in advance!

You cannot have two NICs on the same subnet.

When mounting the share via the IP as in your second line it should work, however I guess since you have two NICs on the same subnet they introduced some problems.

Normally truenas should also complain when you try setting it up this way.

Where did you configure your local DNS entries (binds)?

Oh, I didn’t know that.

I run bind9 on another local machine.

The IPs of the NICs are assigned by a DHCP server which reserved the IPs for the MAC of the NICs.

What is your goal on separating the IPs?

Maybe you want to look into LAGG

Thanks for your suggestion. I will look into it.
