you correct -- ufw configures iptables rules, if try use normal iptables script , ufw ufw tends overwrite rules. can use iptables scripts normal without ufw. or, can add same rules ufw so.

code:

ufw allow 80/tcp

this allow port 80/tcp on interface.

can further specify this

code:

ufw allow 192.168.0.3 192.168.0.5 port 80 proto tcp

this allow traffic 192.168.0.3 destined 192.168.0.5:80/tcp . substitute either address. can use cidr denote multiple addresses well. consult docs more information.
