[Firehol-support] limiting internet to certain periods of time

I'm doing just that and looks great, thanks. And thank you for mentioning
the blacklist helper, very useful, especially for its stateless
capabilities. I have a question about it: the gw/fw is also providing dhcp
for the lan. During those given times I want hosts not to go online, but I
still need them to be able to use dhcp etc. Can the blacklist be applied
somehow to the outgoing/internet facing interface? I saw there is an inface
attribute, but no outface one, but maybe it doesn't matter and I can just
use inface on the outgoing ones?
