Hello, Well first off the regular expression of Iptables -F will NOT flush the specific tables i.e. nat/manglefilter. However, if you are NOT using those tables it's pointless to -F as there's nothing there. In general it's a good idea and a good habit to get into using.
To test your theory you need some rules in any of those three tables. Do the iptables -F and then run iptables -t nat -L -n you will see the rules are still there.

Yet, in print (like Linux Firewalls book) I often see people wanting to apply -F and -X to *every single table one by one* (e.g. iptables -t nat -F iptables -t filter -F iptables -t mangle -F etc.) Am I missing something? My simple 2 lines above seem good enough to do the trick.
