I’m running TrueNAS SCALE Fangtooth 25.04 [release] on a Supermicro 24-bay 2U rackmount server with 128Gb ram & dual Xeon E5 CPUs.
Everything is working as expected with several iSCSI & NFS shares. However, now I need to add a VM and following the docs on adding a Bridge so the VMs can reach the Truenas host.
I normally do DHCP IP reservations via a pfSense SG-4200 physical appliance, so I originally had a DHCP address reservation set on the truenas primary NIC (ens5f0 - 10G SFP+). I’ve changed that to a static IP address in the NIC itself, tested, and saved and everything came back up as normal (and I can access the host via the newly set static address).
Now, trying to add the bridge, I go back into the primary NIC, remove the static IP address, add the br0 (setting the primary nic as part of the group, add the static IP back in via alias, add the primary nic to the bridge members) save and run the test, which seems to be successful; the br0 shows up, but the traffic activity icon stays pale blue and hovering over it with the mouse, it shows 0 traffic on it, which I somewhat expect. When I click the Save button, however, it pauses all traffic across my entire network (including traffic from 3 different XCP-NG hosts/VMs, my physical pfSense appliance, and a few NUC pcs) for a minute, then reverts all network settings back to their original values (including the static IP on the primary nic: ens5f0).
I have no VMs created, yet. And only 3 apps (all of which are turned off while doing all of this).
Any idea what I might be doing wrong? Or, better yet, where to look to see what might be causing this whole-network weirdness when trying to apply those settings?
