Hi,
The Netfilter/Iptables works on what layers?
Let's talk based on OSI model
If I write a rule like IPTABLES -P INPUT DROP
Will it drop the packets on 2nd layer (link layer)?
If I write a rule like IPTABLES -A INPUT -s 10.2.1.93 -j DENY
Will it drop the packets on 3rd layer (network layer)?
If I write a rule like IPTABLES -A INPUT -p tcp --DPORT 80 -j REJECT
Will it drop the packets on 7th layer (application layer)?
Does it have a default layer to work?
Thank you very much,
Rodrigo Ramos
