Something like: # Don't have a limit on my_trusted_domain iptables -A INPUT -p tcp -s my_trusted_domain.org --dport 22 -j ACCEPT # Don't have a limit the internal net iptables -A INPUT -p tcp -s internal_net --dport 22 -j ACCEPT iptables -A INPUT -p tcp --dport 22 -m limit --limit 2/minute --limit-burst 1 -j ACCEPT iptables -A INPUT -p tcp --dport 22 -j REJECT --reject-with tcp-reset Search iptables manual page for limit :).
