Commenting the line mentioned does *NOT* allow all 192.168.x.x IP's into
your system...while everyone can make mistakes, such an obvious security
hole would not last long with as many sharp eyes as there are on this list.

Remember, packets still have to go through the rest of the rule-chain, and
you're not allowing the packets when you comment the rule, you're just not
blindly denying them anymore.

What commenting the above line essentially does, is treat the commented
private IP range as just another IP on the internet.  With the rule
commented, you're at no higher risk from a private IP than from any other
random IP on the internet at large...
