Ginspect : Generate Inspect
A quote (not from me) from the fw1-gurus mailinglist describes Ginspect as:
If you want to learn how to use fw monitor, then you definitely need to take a look at www.decock.org/ginspect. This web site generate fw monitor filters or tcpdump filters. It’s an excellent tool.
You can judge for yourself at decock.org/ginspect
If you don’t know what fw monitor, tcpdump or CheckPoint is, Ginspect is not for you ;)
I no longer work with Firewalls on a day to day basis, so this is not actively maintained. However, you can always get in touch when it breaks.
