maybe.  I don't have a system with this change compiled in, so I can 
only speculate, and I am by no means a shell scripting wizard.  If that 
line is expecting only a non-error shell return, yes, substituting 
net.inet.ip.fw should work.  If it is expecting a "1" returned (which 
net.inet.ip.fw.enable would have been set to), then no, the script needs 
a bit more tweaking.  like I said, I know enough to read a script and 
understand what it does, but sh is not my thing.
