Change in behavior of libvirt networking

[Jeff Sadowski <jeff.sadowski@xxxxxxxxx>]

I have a freepbx vm. A month ago it was working perfectly.

Then either a patch or me playing with docker broke something. ( I had updated my system before starting to play with Docker

So the logs after the break show as follows

15018 [2023-01-25 18:53:59] NOTICE[32354] res_pjsip/pjsip_distributor.c: Request 'INVITE' from '"My Name " <sip:+(My Phone Number)@(freepbxvm ip)>' failed for '(host ip):26346' (callid: e87aca96e0e926db@(obi200 local sip provider ip)) - No matching endpoint found

15022 [2023-01-25 18:53:59] NOTICE[32354] res_pjsip/pjsip_distributor.c: Request 'INVITE' from '"My Name " <sip:+(My Phone Number)@(freepbxvm ip)>' failed for '(host ip):26346' (callid: e87aca96e0e926db@(obi200 local sip provider ip)) - Failed to authenticate

Since I had started playing with docker and created an ipvlan. I tried removing the ipvlan but the behavior is the same. I do not expect the (host ip) to be in the logs at all since it is not sending that traffic. I can ping the ip of the (obi200) with no issues. That is the device ip I expect instead of the (host ip).

A long time ago when I started using libvirt

I had turned off Network manager on my machine and am using systemd to set up my network.

In /etc/systemd/network/

I have 3 files 1-br0-bind.network, 2-br0-static.network and vr.netdev

# cat /etc/systemd/network/1-br0-bind.network
[Match]
Name=enp34s0
[Network]
Bridge=br0

# cat /etc/systemd/network/2-br0-static.network
[Match]
Name=br0
[Network]
Address=192.168.0.7/24
Gateway=192.168.0.1
[Resolve]
DNS=192.168.0.7 8.8.8.8
Domains=my.domain

# cat vr.netdev
[NetDev]
Name=br0
Kind=bridge
MACAddress=aa:bb:cc:dd:ee:ff

enp34s0 is my onboard ethernet

All my vm's used bridge type and connected to br0

Freepbx seems to be a little more picky.

For now a solution that worked for me was to use a second ethernet card for my freepbx vm to use. Instead of bridge mode I selected direct attach. But I would like to solve what happened so I can move it back to my bridge interface I had set up for my vm's.
