Last post by pfry - November 26, 2025, 02:55:33 PMQuote from: AdSchellevis on November 26, 2025, 09:00:11 AMNot at all easy to integrate (lots of moving parts)[...]
In context I wouldn't consider it particularly difficult, but it's not basic. Identifying all of the affected elements would be a pain, especially if they're not well encapsulated (as nobody does that).
Quote from: bimbar on November 26, 2025, 12:05:38 PMI also think that VRFs are not that useful in firewalls[...]
I'd disagree there. But I will grant that it's a bit of a niche feature, and not popular with the OPNsense base. Part of the reason for that is that for most scenarios rule-based forwarding would work about as well; another part is the chicken/egg problem, but that merely partially contextualizes the lack of demand. From a cost-benefit value standpoint it looks pretty dead.

General Discussion / Unexplained behavior - no inte...
Last post by headbanger - November 26, 2025, 02:30:23 PMI am not new to opnsense. I have been using it almost a year. Yesterday I made a change that caused all internet access to be lost on my vlans. Let me first explain my setup. On my box the first physical port is the LAN interface. It is used only to administer opnsense and normally has nothing connected. The second is the WAN port. It connects directly to the ISP's modem. The third port connects to my old consumer WiFi mesh network. I use it for guest access and phones. The third connects to an access point and is used for most iot devices. The fourth is my vlans. It connects to an ethernet power adapter. Then at various points in the house I have other power adapters that connect to smart switches. In my office I have one vlan for my wired linux computers, another for my wired windows computers. In my wife's office I connect to an access point for her windows laptap. The wired computers do not use dhcp, the laptop does. Opnsense captures all port 53 requests and routes them to 127.0.0.1. Unbound then routes them over DOT to a DNS provider.
Yesterday my daughter was visiting and working. Her employer uses Microsoft teams. I had to open some ports on the guest interface so she could work. She was happy. Later my wife reported she had no internet access. Hugh? I didn't change any of the vlan interfaces. To get her going I connected her computer to the phone WiFi. Later I noticed none of the vlans in my office had internet either. Although it shouldn't matter I disbled the rule I added earlier in the day on the guest interface and vola! Internet access returned to all the vlan interfaces. Hugh?! I then reactivated the rule and internet access was still there. Now I may not be a newbe but I am no expert either so I figured let me put this out there to see if anyone out there has any idea what happened.

Last post by wirehire - November 26, 2025, 02:21:36 PMKannst du das mit der flaoting regel noch mal erklären? wenn du jetzt zb floating regel src 10.10.10.10 erlaubt web ports. dann würde das ja auch zb durch den tunnel gehen, weil sie zuerst greift. oder sehe ich das falsch?
und ja , absolut richtig immer auf den wg interfaces / gruppen, ein block , damit egal was ein anderer freiguibt , es nicht ohne extra regel anzulegen , geblockt wird.

Kritisch wäre, wenn auf "Deiner" Seite eine Floating-Regel etwas erlaubt, weil die vor den Interface-Regeln greifen. Wie gesagt, um das zu verhindern, nutze ich immer eine Interface-Gruppe für die "Nicht-WG" Interfaces (=VLANs) und nutze die in den Floating Regeln.
Ansonsten immer am lokalen Ende des WG-Tunnels filtern, der "andere" kann ja erlauben, was er will.

Genau durch die Floating regel ist es mir aufgefallen. Ich habe jetzt die Floating regeln jeweils angepasst.

Danke noch mal an euch, dass ihr mir den Knoten im Kopf gelöst habt!

dann würde die regel greifen, durch den vpn bis rübe rzur seite zwei.
Und jetzt block nötig oder wnen nicht erlaubt, dann kommt es nicht durch?
Ich mache die Regeln selbst immer auf dem VPN Interface, auch wenn ich die Kontrolle für beide Firewalls habe.
So kann man auf einen Blick sehen, was per VPN rein kommt und was nicht.
Floating Regeln nutze ich garnicht, bevorzuge es die Regel da zu lassen, wo sie hingehört

Announcements / OPNsense 25.7.8 released
Last post by franco - November 26, 2025, 12:17:59 PMHey,
So we are making way for safer command execution since a comment was
added to the certification of the business version about a possible
injection into interfaces_pfsync_configure() -- note that it was a comment
and not a security issue since the exploit requires to edit the config.xml
and/or do a configuration import.
The issue in interfaces_pfsync_configure() has now been fixed, but as
mentioned the idea was to get rid of these problems once and for all so
the Shell class was rewritten and every call was audited. You will see
more movement on our way to 26.1 in this area as we do not want to push
all changes into the 25.7 series immediately so that they can be properly
verified first. Suffice to say most of the code we worked on over the
years was already much safer due to the introduction of exec_safe() very
early in the project history.
The Unbound blocklists feature formerly known as a business feature is
now a community feature. Since this required merging both the existing
community one with the business one you need to make sure to reapply the
blocklist settings after the reboot since it will not generate a new and
possibly incompatible format. Make sure to check your automatically
migrated settings while at it.
What does all of this mean? It means security matters. It also means
that community matters. We will continue to improve the community version
because it is the base for the business version and that is exactly how
it should be so that everybody can benefit from these changes!
Note this release includes a new kernel with a lot of improvements in the
vtnet(4) driver department. It is stable code according to release
engineering procedure but if you are seeing specific issues let us know.
Here are the full patch notes:
o system: defaults: properly delete empty model containers in the configuration
