linux - how to limit traffic if port different than 8080?

I'm using this rules to slow down nmap scan

iptables -A INPUT -p tcp -i eth0 -m state --state NEW -m recent --set
iptables -A INPUT -p tcp -i eth0 -m state --state NEW -m recent --update --seconds 30 --hitcount 10 -j DROP
iptables -A FORWARD -p tcp -i eth0 -m state --state NEW -m recent --set
iptables -A FORWARD -p tcp -i eth0 -m state --state NEW -m recent --update --seconds 30 --hitcount 10 -j DROP

It works well , but the port 8080 have big activity and I want to ignoe it in the hitcount.

I want to have somethingn like that:

iptables -A INPUT -p tcp --dport!=8080 -i eth0 -m state --state NEW -m recent --set

Thanks

You can do this using either by writing your rules like:

iptables -A INPUT -p tcp -i eth0 -m state --state NEW -m recent --set
iptables -A INPUT -p tcp -i eth0 -m state --state NEW -m recent --update --seconds 30 --hitcount 10 -j DROP

iptables -A FORWARD -p tcp ! --dport 8080 -i eth0 -m state --state NEW -m recent --set
iptables -A FORWARD -p tcp ! --dport 8080 -i eth0 -m state --state NEW -m recent --update --seconds 30 --hitcount 10 -j DROP

or alternatively, you can add new rules for the excluded ports (BEFORE your rules):

iptables -A INPUT -p tcp --dport 8080 -i eth0 -m state --state NEW -j ACCEPT
iptables -A FORWARD -p tcp --dport 8080 -i eth0 -m state --state NEW -j ACCEPT

The second way will make it easier for you to add more exceptions.
