Even in the current situation (third-party repos can only be added using the console), reports about "OPNsense issues" which turn out to be caused by packages from third-party repos are not uncommon. People report issues they're having with basic stuff like updating OPNsense and don't even mention that they have added a third-party repo (which causes the issue in the first place).

What some users don't seem to realize is that an OPNsense plugin is not some kind of "app". There is no sandboxing, no permission management. A plugin can arbitrarily modify the system and cause issues in other parts of OPNsense. It can even prevent the system from booting.

In my humble opinion, adding a third-party repo is a "not eligible for community support" criteria. It's your system, you can of course do what you want with it, but you really need to be aware of the consequences. If you discover a bug, you need to reproduce it on a system not tainted by a third-party repo before reporting it.
Making it possible to add third-party repos through the GUI would make it even harder to communicate that.

So I'm with Franco here: If adding a third-party repo via the console is too hard for some, that's actually a good thing. It protects them from modifying the system in ways they're not even aware of.

Für das Heimnetz bin ich persönlich auch ein Freund von Konsolidierung und Virtualisierung. So wenig Hardware wie möglich, nicht zuletzt wegen des Stromverbrauchs.

Mein gesamtes Heimnetz - Switch, GPON-ONT, WLAN-AP, OPNsense, File Server, mehrere RIPE Atlas Probes, LTE-Modem, USV, Freifunk, Smart Home Controller, Hue Bridge, DECT (bestimmt habe ich etwas vergessen) - habe ich mittlerweile auf 32 Watt gedrückt. Und da ist noch Luft nach unten, die nächste Optimierung ist schon geplant. :)

Aber ich stimme Patrick zu, dass man nicht zu viel auf einmal anfangen sollte. Gerade die Konstellation "keine Erfahrung mit OPNsense und keine Erfahrung mit Virtualisierung" sorgt bei vielen schnell für Frust.

When used in firewall rules, OPNsense itself doesn't expand these _network / _address aliases at all.

Have a look at Firewall: Diagnostics: Statistics: rules. If you selected an _address or _network alias in a firewall rule, it turns into something like vtnet1:2 or vtnet0:network:1 in the resulting pf rules.

... or if you want to use the additional IPv4 addresses for local services on OPNsense, you can configure additional loopback interfaces with them.
... or if you want to use them for NAT, you can add them to the WAN2 interface using virtual IPs.

So it really depends on your use case.

@Bode
"Ingressfilter für MAC-Adressen auf den Switches" alleine reichen nicht. An Switch-Ports, an denen kein Telefon angeschlossen ist, darf auch kein VLAN 10-Egress stattfinden. Wie Du das konfigurierst ist herstellerabhängig, da gibt es unterschiedliche Lösungen.

@Cedrik
Korrekt, der Hyper-V vSwitch ist VLAN-aware und macht auch Ingress-Filtering. Bode möchte nach meinem Verständnis aber ganz ohne Client-Konfiguration auskommen, womit das wohl ausscheiden dürfte.

Du hast eine grundsätzliche Layer 2-Fehlkonfiguration, die es zu beheben gilt. "Herumdoktern" wäre, dies zu ignorieren und stattdessen an anderen Stellen zu basteln.

Quote from: Bode on February 25, 2026, 06:17:35 PMHabe ewig gesucht woran es liegen könnte.
Die PCs müssen entweder an Access-Ports (nur VLAN 1 untagged) angeschlossen oder so konfiguriert werden, dass sie selbst VLAN-Ingress-Filtering machen. Beides ist bei dir nicht gegeben, weshalb die PCs alle Multi- und Broadcasts aus beiden VLANs verarbeiten. Probleme aller Art sind da garantiert, RAs aus dem falschen VLAN ist nur eines davon.

Quote from: Bode on February 25, 2026, 06:17:35 PMIch möchte eine Lösung, womit die PC's ohne Konfiguration in ihr vlan kommen, unabhängig ob ein Telefon davor ist oder nicht, den Telefonen ihr vlan zugewiesen wird und die PC's mobil mit ihrer Netzwerkkarte benutzt werden können.
Konfiguriere die Telefone wie von Cedrik beschrieben, dann sehen die PCs nur VLAN 1 untagged, wenn sie an ein Telefon angeschlossen werden.
Falls Du wirklich die Konstellation hast, dass am selben Switch-Port abwechselnd mal ein PC und mal ein Telefon (+ ggfs. PC am zweiten Telefon-Port) hängt, dann musst Du den Switch in der Tat so konfigurieren, dass er seine Port-Konfiguration dynamisch anpasst (z. B. default Access-Port für VLAN 1 und nur, wenn die MAC-Adresse eines Telefons erkannt wird, zusätzlich VLAN 10 tagged).

An den Link-Local-Adressen von OPNsense herumzubasteln bringt wirklich nichts. Dann empfangen die PCs eben RAs von zwei unterschiedlichen Source-Adressen, aber dadurch ist doch nichts gewonnen. Sie empfangen immer noch RAs aus beiden VLANs. Und es gib sicher auch anderen Multi- / Broadcast-Traffic im VoIP-VLAN, den die PCs abbekommen.
#7
Vielleicht lassen sich die IP-Telefone so konfigurieren, dass sie das VoIP-VLAN nicht an ihren zweiten Port (an dem der PC hängt) durchreichen? Wäre ein naheliegendes Feature, denn genau für deinen Use Case haben diese ja den zweiten Port.

Du solltest jedenfalls nicht versuchen, für ein Layer 2-Problem (nicht sauber getrennte VLANs) einen Workaround auf höheren Layern (z. B. Router Advertisements) zu basteln.

@Patrick Je nach NIC / Treiber / Konfiguration wird das VLAN-Tag ggfs. ignoriert und Windows akzeptiert dann alle Frames. So kommt es zur Vermischung von VLANs. Habe ich auch schon gesehen.
#8
Das hört sich nach einer inkorrekten VLAN-Konfiguration des PCs an. Dort muss die NIC so konfiguriert werden, dass das VoIP-VLAN ignoriert wird.

Das ist ggfs. einfacher, wenn Du auf dem Switch-Port beide VLANs taggst und auf dem PC explizit das gewünschte VLAN (tagged) konfigurierst.

Mit IPv6 und OPNsense hat das alles relativ wenig zu tun - Du hast ein Layer 2-Problem zwischen Switch und Client-PC.

Let me quote myself:

Quote from: Maurice on February 19, 2026, 03:37:10 PMIf you want it elsewhere in the house, you can prepare a conduit yourself and they will use it to run up to 20 meters of fiber inside the house (also for free).

You can also find all of this information on their website, it's pretty well documented.

Quote from: JamesFrisch on February 19, 2026, 06:11:58 PMSo if I wan't to have multiple VLANs with different assigned prefixes, I need Kea.
No. Dynamically assigning a /64 prefix to an interface is done by dhcp6c (via the Track Interface / Identity Association feature) and unrelated to downstream prefix delegation.

Quote from: JamesFrisch on February 19, 2026, 06:11:58 PMOr basically my current setting can be replaced by switching from track interface to Identity Association and from switching from ICE to Kea?
You can switch to Identity Association, but will then have to manually configure Router Advertisements and DHCPv6.
Kea requires a static prefix, so if you have a dynamic prefix and need stateful DHCPv6, you'll have to switch to Dnsmasq or stick with ISC (which imho is the best option for the time being).

I switched from Track Interface to Identity Association and from ISC DHCPv4 to Kea DHCPv4, but keep using radvd and ISC DHCPv6.

Quote from: nero355 on February 19, 2026, 09:31:00 PMCan you choose a different ISP that operates on their network and get one that way ?
Sure. Deutsche Telekom, Vodafone, o2, 1&1 will happily sell you the very same ONT with a slightly customized enclosure and their own logo slapped on it. :)

Quote from: meyergru on February 19, 2026, 10:14:40 PMAs long as you do not have a rate > 1 Gbps, you can use a GPON ONT, because XGS-PON is mostly downwards-compatible.
A GPON ONT can't talk to an XGS-PON OLT, they even use different wavelengths.

Quote from: chemlud on February 19, 2026, 04:57:18 PMThe router would be one level up and to the very WEST. So kind of nightmarish, no matter it CAT6/7 or fiber.
It shouldn't come as a surprise that in-house infrastructure is a responsibility that comes with house ownership. You can always pay someone to do it for you.

Quote from: chemlud on February 19, 2026, 04:57:18 PMExtra question: How deep does Der Gilb dig outside the house? Still 80cm something at least? No microtrenching or so?
That's really something you need to discuss with them. Often, they don't dig a trench at all, but "drill a tunnel".

Quote from: chemlud on February 19, 2026, 04:57:18 PMMaybe I should ask for an ONT to be placed direct at my network-equipment
The ONT is placed by yourself wherever you want. The demarcation point is the passive optical outlet (Gf-TA) installed by Deutsche Telekom. You can ask them to install it in a location of your choice, but will have to prepare a conduit if that's not close to where the fiber enters the building.

Quote from: chemlud on February 19, 2026, 04:57:18 PMfirst floor, so the fiber would be on the OUTSIDE of the house, before entering through the wall
You can always ask. They sometimes even install the Gf-AP (box where the external fibers end and the fiber going to the Gf-TA starts) on the outside.

@meyergru Deutsche Telekom does not give you a free ONT. You have to buy or rent one.

In single family homes, Deutsche Telekom by default installs the optical outlet ("Glasfaserteilnehmeranschlussdose" in prototypical Telekom speech) in the basement - for free.

If you want it elsewhere in the house, you can prepare a conduit yourself and they will use it to run up to 20 meters of fiber inside the house (also for free).

If you decide to have the optical outlet in the basement, you can then either run your own fiber from there to wherever your network gear is and place the ONT there, or you can place the ONT in the basement and run twisted pair from there to your router.

February 19, 2026, 02:59:07 PM
In automatic mode ("Allow manual adjustment of DHCPv6 and Router Advertisements" not enabled), ISC DHCPv6 has always been active and RAs have always been set to assisted. This is not new.

Quote from: JamesFrisch on February 19, 2026, 02:40:59 PMWe are not talking about prefix delegation on the WAN, right?
No, this is about downstream prefix delegation - OPNsense delegating prefixes to DHCPv6 clients in the LAN. Dnsmasq doesn't support this at all, Kea only with static prefixes.
