In fact, isn't what I wrote ?

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 ?
You can have a default drop rule on all input traffic, then add a couple
of specific rules to allow it from your local network, and another to
allow it from a specific address.
