Better would be a rule to forward their connection to a honeypot / tarpit

You don't have to have it forward to a separate box for the tarpit to work.
Tarpit rules can be placed into the firewall so that any packets from a
particular host (or network) get tarpitted, while allowing everyone else's
to come through to the listening daemon. You just have to give it a specific
source and port. The following would tarpit port 25 (TCP) for the IP address
99.99.99.99, while allowing everyone else through to the listening SMTP
daemon:
iptables -I INPUT -s 99.99.99.99 -p tcp --dport 25 -j TARPIT
Would you please give details on a TARPIT rule?
So it's just a matter of adding rules per each host that causes a problem.
Is there a risk of self DDOS'ing ?
