I just upgraded to 23.1.7_3 from an earlier 23.1.x release. Now, my clients get the DNS servers listed under System -> Settings -> General and not the interface IP (e.g., 192.168.10.1).

Under System -> Settings -> General, I've always had Cloudflare IPV4 and IPV6 servers listed for system use. For my main DNS, I have NextDNS CLI installed on port 53, then Unbound on port 5555.  NextDNS CLI forwards all local domain lookups to Unbound. This works great and I've been doing this forever.

Under Services -> DHCPv4 -> VLAN ID, I always left the DNS fields blank. This has always worked well by providing the Interface IP to each client. From the help, I understand that this is the expected behavior. For example, VLAN 10 is 192.168.10.0/24. It always handed out 192.168.10.1 as a DNS server.

Since the upgrade, all clients now get the Cloudflare DNS servers from System settings instead (with no ad blocking) unless I manually input the interface IPs in each DHCPv4 server. This isnt a big deal, but I cant figure out why the behavior changed. Is it because I use Unbound on a port other than 53? Or something I missed in changelogs?

Have experimented with various things like removing System DNS servers, various check boxes, etc. Nothing really changes this.

Any thoughts on why this changed all of a sudden?

Thanks.

Running 22.1.10 as a VM in Proxmox on a new 4 port i225 mini PC with a Linux Bridge for WAN and a Linux Bridge for LAN. No pass through.  I have Xfinity internet, a handful of VLANs, and I do not run IPS/IDS.

Over the last two weeks, every few mornings, I wake up to no internet. When I connect to Proxmox, I see the OPNsense VM sitting with a yellow pause symbol saying "Internal Error."  If I try to goto a console view, all I see is similar to the screenshot below. The last few log entries before I restart it are all netflow maintenance items. Then nothing.

The weird part is that the error messages in the screenshot are always showing vlan50. This vlan is identical in every way to other vlans I have setup. I've verified firewall rules, RAs, interface settings, etc.

If I restart OPNsense, everything comes back. I'm struggling to get more information on the crash.

I *think* this started with the most recent release, but I'm not entirely sure. This setup was running great the last few months.

There are some other forum posts about flapping WAN connections in recent builds, but I'm not sure if they're related or not.

Anyone have any ideas?
