Dann würde ich testweise mal A-Record anschalten und einen der SIP-Server, z.B. hno002-l01-mav-pc-rt-001.edns.t-ipnet.de. mit SIP per UDP Port 5060 hart eintragen.

Unabhängig davon würde ich schauen, ob der DNS-Service wirklich richtig liefert oder testweise einfach den Unbound von OpnSense nutzen.
Du kannst ja das Device auch statisch konfigurieren - es muss ja nicht den "normalen" Technitium-Service nutzen.

Intrusion Detection and Prevention / Re: Suricata with os-stunnel

Last post by JohnnieDYow - Today at 03:15:51 PM

I guess Stunnel is a Userland proxy, meaning any traffic it receives and forwards, will most likely not be reinjected into the kernel space (e.g. so PF or Suricata can see it), but copied directly on the outgoing interface.

You could probably put another router between the Stunnel OPNsense, and the LAN, which acts as a transparent IPS bridge:

https://docs.opnsense.org/manual/how-tos/transparent_bridge.html

What do you want?' sounds more direct and can be rude in some contexts, while 'What is it you want?' is slightly more formal or neutral

Steht bereits auf NAPTR/SRV ;)

NAT-Traversal ist aus, STUN ist aus.
Hatte ich aber alles schon an.

Ich hatte mal den SIProxd konfiguriert, da registiert sich die Base an der OPNsense aber das wird nicht zu tel.t-online.de weiter geschoben.

Eventuell habe ich ja ein allgemeines Verständnisproblem :D

Last post by falken - Today at 03:07:32 PM

You will need to add a subnet to your clients-all policy.
For example, 192.168.1.0/24 (and your IPv6 subnet on a separate cloned policy) ; Now that list will apply to everything on that subnet and your localhost policies will work to not block from localhost.
If you leave it as blank, it will be evaluated regardless on top of your other policies.  You essentially saying this policy is for EVERYTHING by leaving it blank.

For what it is worth, I think it should work the way you assumed it would, but it does not. :)

Aha. Laut dieser Dokumentation musst Du den richtigen DNS Mode wählen:

https://documentation.grandstream.com/knowledge-base/dp750-administration-guide/?asp_highlight=DP750&p_asid=2#post-22767-_Profiles_Page_Definitions

Die SIP-Server-Einstellungen werden demgemäß verwendet. Möglicherweise steht das aktuell auf "A Record" statt auf "NAPTR/SRV".

Es gibt da noch viele weitere Einstellungen, z.B. "NAT Traversal" und "SIP Transport".

Last post by connervt - Today at 02:47:53 PM

I also recently replaced my ISP's cable modem /w a Netgear CM2000 which meets and exceeds the specs of the ISP's modem.

I would start here.  Plug your modem directly into a known good computer and test.

When troubleshooting, I have always been from the school of "What was the last thing changed?"

Da löst er ja die Adressen richtung 217.0. auf - Das sind ja die Telekom Registar Server.

Doof ist auch das man die Kisten nicht anderweitig testen kann, kein Telnet auf 5060, kein Ping, nix...

If they are meant to cascade, is there a way to make the policies work like pf 'quick' rules, on first match?  Alternatively, can anyone think of a creative hack to make this scheme work as intended and still support dynamic prefixes? :)

I am looking for the same info.... It would be great if the Blocklists rules worked like firewall, the first match wins. Also would be great if dynamic prefixes could be used as source lists.

Stimmt die Konfiguration des Grandstream in Bezug auf den DNS-Server vielleicht nicht? Bekommt er den Technitium-Server per DHCP?

Oder ist der DNS-Server nicht erreichbar? Firewall dazwischen?

Ich hatte die aufgelösten SIP Kisten der Telekom auch schon händisch eingetragen - Auch ohne Erfolg.
Das Log ist ja auch nicht wirklich aufschlussreich, er meldet zwar das "Unreachable" - Aber nicht warum oder wo die Verbindung nicht zustande kommt.
Das die OPNsense hier das Thema ist glaube ich auch nicht wirklich.

Eine Fritzbox habe ich nicht, will ich mir zum testen aber auch nicht anschaffen ;)
