Could someone please explain this output?

Hi,

	Here is what I get on my Potato system :

#ipchains -L input
Chain input (policy DENY):
target     prot opt     source                destination           ports
ACCEPT     all  ------  anywhere             anywhere              n/a
DENY       all  ----l-  127.0.0.0/8          anywhere              n/a
ACCEPT     all  ------  localnet/24          anywhere              n/a
DENY       all  ----l-  localnet/24          anywhere              n/a
ACCEPT     all  ------  anywhere             _my_hostname_here
n/a
ACCEPT     all  ------  anywhere             255.255.255.255       n/a
DENY       all  ----l-  anywhere             anywhere              n/a

	How do I interpret this output? For example, the lines handling
the source = localnet/24 - will they let a packet from outside pass in or
be rejected? Why are there two lines? This configuration is the result of
me doing a 'apt-get install ipmasq' - so there really hasnt been any
customization by me.

Thanks,
Jor-el
