Iptables :: priority of rules

[Luc MAIGNAN]

Hi all,

I don't understand how the priority of the rules of iptables is set.

My problem : I want to allow ssh from my local network(1), and from 
outside only for an IP(2)

So i Wrote :

(1) : iptables -I INPUT -p tcp -s 192.168.0.0/24 --dport ssh -j ACCEPT
(2) : iptables -I INPUT -p tcp -s ! x.x.x.x --dport ssh -j DROP

The result is that I can ssh only from the ousided IP, not from local 
network. If I switch the two rules, the result is the same.

Can anyone help me to understand ?
