Normal behavior. The second rule shadows the first, and you have 'check for
rule shadowing' enabled, which it is by default. Catch all rules should go
towards the bottom.

I know this works too. How are you trying to do it? Are you trying to allow
pings to the firewall or through the firewall?

Have you checked the box "consider firewall part of 'any'"?
(This setting makes a big difference)

Using the wizard to make a 'quick firewall' will give you something to look at
as an example. Looking at the script output from the program will help you
learn what the program generates in response to a rule.

If you haven't read the whole manual for fwbuilder, you should.
