MariaDBローカルエリアネットワーク内の別端末からアクセス出来ない

ローカルエリアネットワーク内にあるデータベースサーバーへ別端末からアクセス出来なくて困ってます。

やりたいこと

端末からmysql -h 192.168.100.160 -P 3306 -u dbuser -pでデータベースへアクセスできるようにしたいです。

環境

データベースサーバー：192.168.100.160
接続したい端末:192.168.100.16

各設定

MariaDBの出力

console
1MariaDB [(none)]> show variables like 'port';
2+---------------+-------+
3| Variable_name | Value |
4+---------------+-------+
5| port          | 3306  |
6+---------------+-------+
71 row in set (0.002 sec)
8
9MariaDB [(none)]> select user, host from mysql.user;
10+--------+---------------+
11| user   | host          |
12+--------+---------------+
13| dbuser | 192.168.100.% |
14| root   | localhost     |
15+--------+---------------+
162 rows in set (0.001 sec)

ポート開放の設定

console
1ryou@dbserver:~$ sudo ufw status

4To                         Action      From

622                         ALLOW       192.168.100.0/24
73306                       ALLOW       192.168.100.0/24

この状態でSSHのアクセスは出来ているので問題は無いと思います…

追記

/etc/mysql/mariadb.conf.d/50-server.cnf　に設定ファイルらしきものを発見して、回答いただいた記述を追加しました。
bind-address = 127.0.0.1は元々あったのでその下に一行追加した感じです。
