Virtual private networks / Re: Wireguard Selective Routing With Mullvad
March 24, 2026, 07:38:58 AM #2
Virtual private networks / How can I perform selective routing from the local system?
March 23, 2026, 01:08:42 PM
wg1: flags=10080c1<UP,RUNNING,NOARP,MULTICAST,LOWER_UP> metric 0 mtu 1420
description: Mullvad
inet 10.x.x.x netmask 0xffffffff
groups: wg wireguard
Selective routing has been configured, and traffic from specific hosts (192.168.10.0/24) is successfully being routed through Mullvad WireGuard.
vm(192.168.10.5) -> curl ifconfig.co -> show mullvad ip
However, it seems that traffic from the OPNsense machine itself through the wg1 interface is not going through Mullvad.
curl --interface wg1 ifconfig.co
> show wanip
How can I enable Mullvad routing from OPNsense (local)?

26.1 Series / Re: OPNsense System Tunables Configuration
March 17, 2026, 08:13:56 PM
I also performed tuning by referring to that repository. Rather than simply copying it, I asked Gemini and ChatGPT what each configuration parameter does and which values would be suitable for my hardware specifications, and adjusted the settings based on that.

I didn't see it when I checked a few days ago, so that's good news.

26.1 Series / Can we expect FreeBSD 15.0 (15.1) in v26.7?
March 17, 2026, 01:16:10 PM
v24.7 - freebsd 14.1 (July 25, 2024)
v25.1 - freebsd 14.2 (January 29, 2025)
v25.7 - freebsd 14.3 (July 23, 2025)
freebsd 15.0 release (December 2, 2025)
freebsd 15.1 release schedule (June 2, 2026) - https://www.freebsd.org/releases/15.1R/schedule/
There are many changes in FreeBSD 15.0+, but the things I'm looking forward to are the following.
- umb, umbctl (for cellular modem backup)
- amneziawg
- openzfs 2.4.0
v25.1 - freebsd 14.2 (January 29, 2025)

General Discussion / How can I log in to the console TTY without using TOTP?
March 04, 2026, 08:55:57 PM
You cannot view this attachment.
Is it possible to require TOTP only for web logins? I would like local shell logins to use only a password.

Has anyone upgraded the firmware in Proxmox? Nothing is being displayed in nvmupdate64e.

For optimal performance, I configured the settings as shown in the image and rebooted. However, when verifying via the `sysctl `command, it shows up as `C1`.

Even if FreeBSD supports it in kernel mode, does it still require separate work on the OPNsense side?

don't user ids/ips
low traffic
I haven't changed any settings, but looking at the monitoring graphs, RAM usage definitely went up after the 26.1.1 upgrade.

- disable host discovery
after upgrade 26.1 to 26.1.1
While the absolute amount is small, percentage-wise, it seems to be about a 50% increase. Usually, it hovers in the low 1000MB range.

It seems that we need an Intel Partner account to download the latest firmware.
