This is a shameless plug for my syslog parsers.
You can find them on https://github.com/hvdkooij/syslog2checkpoint and in particular the iptables parser works rather well for me.
My home router (ASUS RT-AC68U) can send syslog to a SmartCenter I have externally in my lab and I have full insight on what is going on my home network this way.
Unfortunatly I have no longer a Barracuda Email Security Gateway in my lab so I can't play with that.
Anyone willing to tinker with a syslog parser for Check Point feel free to contact me.
