Hello adam_blackice. Could you please clarify a bit? It's hard to understand your question. Inbound traffic is any traffic headed in your direction, but I'm not sure if that's what you are asking or not.

thanks for your replay

let us take the iptables as an example for what iam taking about if we say that the we want to make an INPUT rule that will drop icmp requests so we are going to make that in the filter table under INPUT chain

> my questions is could we say that the INPUT chain it's also inbound chain also as you said that the inbound is any traffic

destined to inside the network

You are correct. Traffic is classified based on whether it is "inbound to," "destined for," "merely passing-through," or "departing from" this computer. The documentation for IPTABLES et al tells all...

Sort of. It's best if you don't think of inbound traffic as belonging to a certain chain. Yes, in the case of the INPUT chain, the packets traversing it are indeed inbound - but only toward the host itself - NOT the network. Inbound traffic headed into your network would traverse the FORWARD chain instead.
