There have been some changes upstream in FreeBSD that should be of interest here, both in STABLE 14 & 15:

- https://reviews.freebsd.org/D51475 sctp, tcp, udp: improve deferred computation of checksums
- https://reviews.freebsd.org/D51686 vtnet: fix translation between mbuf and virtio flags

[added as this thread is one of the top google searches related to freebsd tcp offload & checksum - I hope that's helpful for somebody]

Es war wirklich ein Verständnis Problem. Unifi Bezeichnet das alles komisch. Mir hat das Grundverständnis von OPNsense einfach gefehlt, ich habe es mitlerweile verstanden. Sorry :)

ist sozusagen solved

26.1 Series / dnsmasq not using specified dn...

Last post by crt333 - January 30, 2026, 03:40:21 PM

I have a vlan that routes all traffic through a wireguard tunnel.  In dnsmasq I had been using dns-server[6] option to specify the use of the wireguard dns server in the tunnel, rather than the opnsense dns server. This worked before the upgrade, but now that vlan is just using the opnsense dns, rather than the specified server. I deleted the old DHCP option, and re-entered this on the specific vlan interface, but it still doesn't work.

Suggestions?

Now only 5.8G is used? Before grow it was 14G ...
Why was /var/db so big?

Maybe this : https://forum.opnsense.org/index.php?topic=50590.0
Was the reason ?!

And of course that wasn't the fix at all. Tried pretty much everthing, but apparently is the intel 226-v Nic combined with freebsd and QUIC a very poor combination. Apparently, linux handles it nicely enough so it isn't noticed, but freebsd doesn't and exposes the problem.

I can't be the only one facing this problem with this Nic, ipv6 and QUIC. I know, I know, just block UDP 443 and everything is fine. But that's just a quick and dirty trick. Would be nice if this could be handle nicely by freebsd.

Code Select Expand

vlan0.2: 9 / 192.168.2.1 / 192.168.2.255
vlan0.4: 11 / 192.168.4.1 / 192.168.4.255
vlan0.5: 12 / 192.168.5.1 / 192.168.5.255


Slightly offtopic, but even tho this isn't a CISCO device their 'Best Practice Guides' do advise to skip VLAN 0 to 5 when setting up your network so when you feel like it please look into that and decide if you want to change your network setup or not :)

Last post by nero355 - January 30, 2026, 03:22:55 PM

After reading it all, i have ordered a TP-Link TL-SG105E. This should hook me up properly.

Usually the 8-port version is pretty much the same price, but the 5-port version is OK too ofcourse! :)

When ZenArmor is installed, best to wait until they release a version compatible.

Also make sure you back up your config file and make a snapshot of the VM (or physical).

I might do this on my lab so I can fight through the DHCP changes before Business gets this in a few months and I upgrade production.
