iptables -D INPUT -p tcp --dport 8080 -j ACCEPT

Delete a specific rule from the INPUT chain

Removes the rule that allowed TCP port 8080; the rule text must match the added rule exactly. Deleting by spec works for one rule, while iptables -D INPUT 3 deletes by position. Check iptables -L --line-numbers for the index.
