Hi,
I'm new to linux so i try to learn now,

I'm trying to add some rules for my firewall,

Can enlighten me please?(DDWRT 26138)


Iptables -A INPUT -m state --state INVALID -j DROP
Iptables -A INPUT -p tcp ! --syn -m state --state NEW -j DROP
Iptables -A INPUT  -p tcp --tcp-flags ALL ALL -j DROP


-Do i have to leave a space between each lines?(or write a #Comment before each lines?)

-Do i have to change the order any lines?(-m,-p,! confuses me)

Thank you,

what firewall rule are you trying to write? are you trying to separate ip from talking to each other?
