David Latorre commented on FTPSERVER-349:
-----------------------------------------

Hello  Devnull,

When i first revised your patch I noticed this problem. I considered some possibilities you
haven't mentioned: 
-1. In the method that adds the subnets/ips to the WhiteListFilter  (   updateWhitelistFilter(),
right?) we can remove the filter from the chain if we have an empty subnet list.

This would work but I'm concerned that ftpserver users may want to use WhiteListFilter when
it is not in the chain.

-2. Explictly  check for the address 0.0.0.0/0 and consider it to mean "all addresses allowed".


If we move the WhiteListFilter to MINA-core, it might be worth discussing there how to signal
that "all addresses are allowed".


What do you think, Niklas?
