Bridge interface creation causes no internet connection

TrueNAS General
1

Hi,

I have a TrueNAS instance (25.04.2.6).

I have configured a SMB share and created a VM that must access the SMB share.

This is my network configuration:

  • 192.168.1.1 –> fritzbox router

  • 192.168.1.2 –> adguard home

  • interface #0: enp116s0 –> DHCP (ip address: 192.168.1.8/24)

  • interface #1: br1 –> with enp116s0 bridge member (no ip address)

  • global configuration: nameserver is 192.168.1.2

In the current state TrueNAS seems unable to connect to internet (e.g. I cannot send test alert mail or check for updates; it fails with: [Cannot connect to host update . ixsystems . com : 443 ssl:default [Temporary failure in name resolution]]). While the VM can see the SMB share.

If I remove the bridge interface TrueNAS is now able to reach internet (i.e. I can search for updates and send email) but the VM is no more able to access the SMB share.

Is there a way to fix this?

Thanks!

Remove the ip from the interface & add it to the bridge.

Hi, thanks for your reply. The enp116s0 is configured with DHCP. Can I configure the br1 to dhcp and leave enp116s0 blank?

That is fine enough; as long as the bridge members have no ip & the bridge is the one with the IP.

Only concern with dhcp is if you randomly have something else assigned down the road & have to guess what ip to use for the web interface & smb share.

Thanks, I have checked and now everything works as expected. Thank you very much!
