Very true. I do prefer writing this to explicitly allow only packets
from/to 127.0.0.1/32 though:
IPFW syntax
-----------
add allow ip from 127.0.0.1/32 to 127.0.0.1/32 via lo0
add deny ip from 127.0.0.0/8 to any
add deny ip from any to 127.0.0.0/8
ipfilter syntax
---------------
block in from any to any
block out from any to any
pass in quick from 127.0.0.1/32 to 127.0.0.1/32 on lo0
pass out quick from 127.0.0.1/32 to 127.0.0.1/32 on lo0
I've even been tempted to try blocking everything on lo0 and explicitly
allowing only a few selected ports/protocols. But that's paranoid :-P
