# switch -L : List all
# switch -D : drop a defined rule
#// iptables -D INPUT 2 would drop the second rule in the list
#
# A valid input chain to allow all on port 80 would look like this:
# // iptables -A INPUT -p tcp --dport 80 -j ACCEPT
# this means all traffic on tcp port 80 is accepted
#
#
#
# lso I would recommend apt-get install iptables-persistent to help save and reload the rules automatically.
