Sudo ufw [--dry-run] [delete] [insert NUM] allow|deny|reject|limit [in|out on INTERFACE] [log|log-all] [proto protocol] [from ADDRESS [port PORT]][to ADDRESS [port PORT]]

Sudo ufw allow proto tcp from xxx.xxx.xxx.xxx to any port 80
webサーバーへのアクセスを許可しない場合
Sudo ufw allow proto tcp from any to any port 80
特定のネットワークからのアクセスを許可する場合
Sudo ufw allow proto tcp from xxx.xxx.xxx.xxx/yy to any port 80
