[yadifa-users] Define source address for transfers

Luckily we did not had this issue although we have multiple IPs configured. Probably our luck was that the Linux default route uses the src IP we wanted to have as query source.
Maybe you can change the default IP of the server to the one you need, and change other daemons to use the respective source IP.
$ ip route get 22.214.171.124
126.96.36.199 via x.x.x.x dev ens18 src Y.Y.Y.Y uid 2001
You might be able to choose the source Y.Y.Y.Y by manually configure the default route and specify Y.Y.Y.Y as source.

While this might not be the solution you're looking for: faced with this problem, we decided to only configure the IP-address from which outgoing requests should originate in the server network configuration. And then activate the other addresses afterwords. We use Rocky Linux with NetworkManager enabled, so activating the other IP's is done with a script in /etc/NetworkManager/dispatcher.d/
If you configure your network on your server that way, all outgoing requests on your server, for which no specific source address is specified, should reliably originate from that same IP-address thus configured during boot time. Any other solution we tried caused the source IP to possibly change after a reboot.
And: if you are using NetworkManager and activate the IP's in /etc/NetworkManager/dispatcher.d/, they should be active before Yadifa starts. So you won't even need to enable "net.ipv4.ip_nonlocal_bind".
This being said: "+1" for the feature request: being able to configure the source address for outgoing requests in the Yadifa configuration.
