Folks,
From the /var/log/asterisk/firewall/log file snippet below, the firewall daemon is complaining that what appears to be every line contains a Deprecated Wait Interval parameter. Seems like this should be removed. From the FreePBX admin screen:
PBX Version: 17.0.19.27
PBX Distro: 12.7.8-2408-1.sng12
Asterisk Version: 21.8.0
This appears to just be filling up the log file, but the firewall is showing as running.
