Firewall Rules
Rule Nb	fr Int.	to Int.	Proto	Source	Port	Dest.	Port	State	Action

Hint:
rules are evaluated on a first-match basis (i.e. the action of the first rule to match a packet will be executed). This means that if you use block rules, you'll have to pay attention to the rule order. Everything that isn't explicitly passed is blocked by default.
