Confusion about iptables configuration

[megajune]

I'm trying to ensure that only the following two networks have access to my web server - running https only.

10.1.1.0/24

and

192.168.1.0/24

Could someone explain to me how this is done? Note, I've never successfully used IPtables before, so feel free to talk to me like an idiot

If needed, my distro is Ubuntu Server 10.4

This should get your started;

iptables -P INPUT DROP
iptables -P OUTPUT ACCEPT
iptables -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT
iptbales -A INPUT -m state --state NEW -s 10.1.1.0/24 --dport 443 -j ACCEPT
iptables -A INPUT -m state --state NEW -s 192.168.1.0/24 --dport 443 -j ACCEPT

This should get your further;

That does it. Thanks!
