Help understanding Firewall builder

I'm currently teaching myself firewall builder and having a great time doing so, however I've hit something I need help understaning.

I turned off "Accept ESTABLISHED and RELATED packets before the first rule" and added a rule to do this myself. The rule reads
Rule 0

Source : any
Destination : any
Service : Established
Action : Accept
Time : any
and it works fine However if I rule 0's change destination to the local machine (btw I'm useing this firewall to protect just the local machine, not a whole network) then every time I try to use the internet my packets get caught by rule 3

Rule 3

Source : any
Destination : any
Service : any
Action : deny
Time : any
This count's for outgoing packets, not too sure about incomeing ones because nothing gets out in the first place. What I don't understand is how come rule two dosn't let the packets out

Rule 2

Source : Local Machine
Destination : any
Service : any
Action : deny
Time : any
Could someone please explain why rule 2 isn't letting packets out?
