Whitelist IPs for ufw

Question

I have set some rules in ufw to rate limit connections, as such:

-A ufw-user-input -p tcp --dport 25 -m state --state NEW -m recent --set
-A ufw-user-input -p tcp --dport 25 -m state --state NEW -m recent --update --seconds 6 --hitcount 12 -j ufw-user-limit
-A ufw-user-input -p tcp --dport 25 -j ufw-user-limit-accept

These are in: before.rules

I would like to white list IPs from being subject to these rules. If I run the command:

sudo ufw allow from 192.168.0.0/24

will this range be white-listed from my rules? Or can this be done another way?

The "answer" to your question is:

sudo ufw insert 1 allow from 192.168.0.0/24

This will put the rule first in your rule set.

The order of rules is critical in ufw/iptables as a packet will match the first rule, subsequent rules are (for the purposes of this discussion) ignored.
