Iptables error after module update

SNG7 12.7.8-2107-3.sng7

FreePBX 15 15.0.17.55

All modules up-to-date

After one of the last updates, unfortunatelly I’m not sure which one, my firewall.log logfile is being constantly filled with the following lines:

1633108567: /sbin/ip6tables -w5 -W10000 -F fpbxsvc-api_ssl
1633108567: /sbin/ip6tables -w5 -W10000 -A fpbxsvc-api_ssl -p tcp -m tcp --dport -j ACCEPT
1633108567: /sbin/iptables -w5 -W10000 -F fpbxsvc-api_ssl
1633108567: /sbin/iptables -w5 -W10000 -A fpbxsvc-api_ssl -p tcp -m tcp --dport -j ACCEPT

Clearly, the command is missing the port definition, so the firewall.err logfile is consecuently filled with the following lines:

ip6tables v1.4.21: invalid port/service `-j' specified
Try `ip6tables -h' or 'ip6tables --help' for more information.
iptables v1.4.21: invalid port/service `-j' specified
Try `iptables -h' or 'iptables --help' for more information.

I’m not sure which update might have caused this, but this same situation is happening in 3 different servers, all of them running the same distro and freepbx version, all modules up-to-date

I guess these might be the relevant modules that might be related to the FreePBX Firewall
