High availability / Re: Some direction for HA conf...
Last post by Machito - Today at 08:50:56 AMQuote from: Lipaz on September 21, 2026, 06:51:53 PMHello,Are you using a virtual switch or dedicated VLANs for those extra interfaces?
before i start, i would love to have links with information on how to, here are some questions i didnt found written documentation on the process.
my goal is two setup 2 VM with OPNSense and i have few question:
* if i want to add another happymod interface, what will be the process?
* is there an option to have 2 interfaces without VIP and use them as management port?
* what is the best recommendation to monitor HA status with remote monitor platform? are the alerts send via SNMP?
thanks

Hardware and Performance / Re: 10G but reaching only 5-5....
Last post by ou1 - Today at 07:53:57 AMQuote from: stanps on Today at 03:04:55 AMI don't see that anyone has recommended this, and it may not be feasible but....you could plug a machine directly in to you ISP's endpoint and do a speed test from there. And then plug directly in to your OPNSense fw and check from there.
You might not have full bandwidth on the public side of your fw. It may not even be an OPNSense issue.
It's definitely not an ISP issue, i get full speed with different machine, same opnsense config and sfp+ modules. CPU on DEC 750 is too slow for 10G, unless there are some config options that we've missed.

26.7 Series / Some observations that may be ...
Last post by erwinvanlonden - Today at 04:07:41 AMI observed some issues with 26.7.4 which caused Unbound to fail and therefore basically killed off my internet access.
This is a home setup so it would not likely to hit businesses that have dedicated hardware.
I run OpnSense in a Proxmox VM with 2 WAN interfaces directly bridged from the hardware into OpnSense as well as 1 LAN interface with around 8 VLAN's stacked on top of that.
By default when you instantiate a VM in a somewhat older Proxmox version, it will attach a x86_64 processor (depending on the underlying hardware). This will become incompatible with some of the later Python libraries such as NumPy which seem to require some fancy processor features that are exposed with newer processor architectures. Therefore when I changed the underlying virtual cpu to x86-64-v2 in Proxmox and rebooted the VM, that problem went away.
Another issue that I encountered was also related to Unbound.
Apparently one of the local network systems had registered with an unsupported hostname "xxxxx." (mind the . at the end) via DHCP. I didn't see this at first and just assigned a static IP address for this system in Kea without modifying the hostname. This causes that hostname to show up in the Unbound static list as well when you have Opnsense configured to do so via the "Register DHCP Static Mappings" setting.
As the "." will cause a concatenation of hostname and domainname resulting in something like "xxxx..example.com". That will cause Unbound to fail as it cannot load an empty zone "..example.com". You'll run into errors like:
```
2026-09-24T22:49:17 Critical unbound [79215:0] fatal error: Could not set up local zones
2026-09-24T22:49:17 Error unbound [79215:0] error: Bad local-data RR xxxxx..example.com IN A 10.10.10.10
2026-09-24T22:49:17 Error unbound [79215:0] error: error parsing local-data at 12 'xxxxx..example.com IN A 10.10.10.10': Empty label
```
After I corrected the hostname and registration in Kea, unbound could start normally.
Not sure if anyone has run into the same issue(s) but it may come in handy to have it posted here for future reference.
Cheers

26.7 Series / ACME cron renewal fails but ma...
Last post by arrowd - Today at 01:38:44 AMI set up the ACME service on my OPNsense (v26.7.4_1 on a Protectli V1410) in the spring. The problem I describe happened at the first cert renewal, but I decided to wait for the next run to see if it repeated. The certificate was due for replacement yesterday but the cron job failed. I then ran it manually and it succeeded without my changing any setting. I have my domain DNS at Cloudflare. My TrueNAS is set up similarly and the ACME runs correctly there. This is apparently a commmon problem on OPNsense as I found at least two separate forum posts saying essentially the same thing. Neither had a solution with people just saying they would renew manually when needed. Do you think this is a permission problem? A Cloudflare problem? Thanks for reading.
Below is the log in debug format. I replaced my domain name with 'mydomainname' and my unique numbers with equal length strings of 'a','b','c','x', or 'y'. The two sets of long log lines between cron/manual runs are identical.

Hardware and Performance / Re: amd-xgbe ("ax"): interface...
Last post by BrandyWine - Today at 01:12:45 AMNeed to look deeper.
EPYC's do have various implementations of the PHY, but I see most (the newer stuff) use the axp driver. The pciconf shows a device ID that supposedly uses the newer AXP code, but technically still from the amd-xgbe module.
I suspect an iflib issue.
What AMD EPYC is it exactly?
https://cgit.freebsd.org/src/commit/?id=7113afc84c0
Quote from: bot0x1458 is indeed the AMD EPYC integrated 10-GbE controller used by FreeBSD's axp driver. The important detail is that FreeBSD's driver was added as an iflib-based driver, and the hardware exposes separate RX DMA queues and management counters. If traffic works but RX counters remain at zero, this is likely a driver/statistics-path problem rather than PCI identification.
