The FORWARD chain is used to manage packets that are being routed through the machine. If the machine is a router then dropping all packets in the FORWARD chain would be bad. If it's not a router then you can drop packets in the FORWARD chain (if they ever get there).

iptables -P FORWARD DROP, good or bad?
I knew this word a long time ago. Then I lost my memory. childhood and all. mva trauma, head injury.. I was good with words before because I was a songwriter, and I had a feeling that this word was etched in my memory somewhere but was just inaccessible.. knowing this word again could solve a lot of consequent problems in writing/overcome writers block to some degree for me.

So here it is: You know how there is an "interval" between say a "train of events"? "Interval" is the best and only word I could think of -closest to this phenomenon- to describe it.

To be a bit more vivid, imagine a train (locomotive) with 10 carriages, and the third and fourth carriage missing above the wheels. So, as the train moves past you, there is a "gap" that transitions through your visual and sound spectrum yes? What is this phenomenon? "Something" (that) passes by you.. It is a very obvious word, but I just can't figure out.. Even after one of you points it out, I might have to give it a memory marker to make it a long term memory- as my short term memory is still not in very good shape (or maybe it's just in the head).

Further, imagine this "gap" or "interval" of sorts streaking past you like a bullet.. What is this phenomenon? :)
