I have a remote location with two Yealink devices.
I have a DNS name added to the firewall as “trusted - excluded from firewall” yet
the ip still get’s banned in fail2ban asterisk-iptables.
I’m running FreePBX 188.8.131.52
I’m not sure what to do to prevent these devices from getting banned.
After adding the hostname, to firewall to I have to manually reload/restart anything?
What can I do to further troubleshoot?
What should I look for in logs?
I do see “Failed to authenticate” for the remote extension, but why is it getting banned. I have
a feeling remote network issues may be causing the failures but I’ll need to do a packet capture
to know for sure.
Should the IP still get banned for failures if it’s excluded in firewall network as trusted?
Well, I do see something interesting:
Request ‘INVITE’ from ‘sip:184.108.40.206’
It seems the phone is not sending the authname, or it’s getting lost somewhere.
