very basic question about labels in iptables


hi there
just a very quick question

small office network with linux braodband firewall running debian.

when i type iptables -vL
i get:
pkts bytes Target prot opt in out scource destination
Chain INPUT (policy drop 1 packets, 48 bytes)
594k 646m ACCEPT all -- eth0 any 192.168.0.0/24 anywhere

i know(think) this line means
accept all protocols from the network to anywhere goint into the box via the internal nic and laving the box through any device?
please tell me if this is wrong.

so my questions are:

what does droplog and TCPMSS refer too in the TARGET column?
what do the packets, bytes and opt columns mean?
what does chain INPUT/FORWARD/OUTPUT/DROPLOG mean?

answers to any or all of these will be much appreciated
thank you
