[Firehol-support] Creating a custom rejection chain with firehol

[Carlos Ferreira]

Hello to all

I'm having difficulties in understanding the mechanism of creating
chains with firehol.

I want to use sshguard with firehol.
When sshguard detects a possible threat, it adds a drop entry to the
sshguard chain, but for this to be successful, the chain must already
exist.

I want to create that "sshguard" chain and use it with the chain of my
WAN adapter, so it immediately drops the packets upon arrival.

Can anyone provide me assistance?
Thank you.
