We have switched our 3cx pbx from Windows to the official 3cx Debian iso.
After the setup I checket iptables configuration and saw that it contains some
preset rules. Unfortunately many of the rules make no sense to me.
Examples:
Now I wonder if this is something specific to our installation or if this is a general issue of the iso.
What is the best practice of 3cx iptables configurations? Stick to the preconfigured rules, adjust/enhance them
or rip the whole config and build it from scratch?

Examples:
- Duplicate entries
- Destination sip.mcast.net in INCOMMING chain
- Accept any any rule in the middle of the rules
