Ich versuche eine Verbindung zwischen einem VPS mit Linux und einer FritzBox herzustellen. Dabei soll der VPS den Server spielen und die FritzBox den Client.

Das Problem dabei: Ich kann zwar die FritzBox vom VPS erreichen, aber nicht die Clients dahinter.

Ursache dafür scheint zu sein, dass die FritzBox die Konfiguration nicht 1:1 übernimmt sondern sie verändert. Insbesondere die IP der FritzBox wird unter Address eingetragen.

Was ich importiere:

[Interface]
PrivateKey = ...
Address = 192.168.198.178/24
DNS = 192.168.198.1

[Peer]
PublicKey = ...
PresharedKey = ...
Endpoint = ...
AllowedIPs = 192.168.198.0/24, 192.168.188.0/24
PersistentKeepalive = 25

Was die FritzBox draus macht:

[Interface]
PrivateKey = ...
ListenPort = 58564
Address = 192.168.178.1/24,192.168.198.178/24
DNS = 192.168.178.1
DNS = fritz.box,192.168.198.1

[Peer]
PublicKey = ...
PresharedKey = ...
AllowedIPs = 192.168.198.0/24,192.168.188.0/24
Endpoint = ...
PersistentKeepalive = 25

Wie kann ich das verhindern oder zumindest erreichen, dass ich die Clients hinter der FritzBox erreiche?

I run a VPS and two locations with modem/router/NAS.

ATM they are not connected and I connect manually from my clients to the networks via individual VPN connections.

Now I want to simplify it a bit. Should I go for headscale or stick to a regular VPN? Anything else I should try or know?

My latest backup failed. I ran integrity check and it also failed.

I tried to delete the latest version, but the X-symbol is grayed out.

What can I do?

Hat jemand hier die FritzBox mit dem Back to Back User Agent von FlexiSIP zum Laufen bekommen?

I want to receive calls from regular phone lines with FlexSIP.

Anyone has a working json for sip-Bridge for PSTN? Examples on web page seem not to work for me.

Ich benutze eine 6860 5G als Ausfallschutz für eine 7690.

Wie verhält sich DynDNS auf der 7690 wenn die Ersatzverbindung aktiviert wird? Wird dann die öffentliche IP der 6860 5G registriert?

If there is a better place to ask about FlexiSIP, please tell me!

I just started with FlexiSIP. I use a Debian Trixie VM, everything is on the local network at the moment. Server has a static IP, clients have dynamic but fixed IPs.

Following the official documentation from their web page I installed the proxy. I installed redis and iptables in addition.

I took the basic configuration from https://wiki.linphone.org/xwiki/wiki/public/view/Flexisip/HOWTOs/Minimal%20registrar%20with%20authentication/ and added the redis configuration from https://wiki.linphone.org/xwiki/wiki/public/view/Flexisip/HOWTOs/TLS%20access%2C%20Registrar%20with%20Redis%2C%20authentication%20from%20database%20and%20media%20relay/.

The server starts up without errors, all softphones connect successfully. But when I try to call someone I receive a "User not found" on the client (I can find it in the contacts though)

There is no message in the logs.

Where do I start to analyze this situation?

I run a split tunnel VPN on my phone - 192.168.178.1/24 to the VPN tunnel to the Fritz Box and everything else to the cellular network.

When I call someone with Fritz Fon app it rings but we can’t hear each other.

What could be the cause?
