我试图远程访问我的mysql/mariadb服务器，但它一直拒绝我的访问。以下是我的设置：
iptables-l

Chain INPUT (policy ACCEPT)
target     prot opt source               destination
ACCEPT     tcp  --  anywhere             anywhere             tcp dpt:mysql
ACCEPT     all  --  anywhere             anywhere             ctstate RELATED,ESTABLISHED
ACCEPT     all  --  anywhere             anywhere
INPUT_direct  all  --  anywhere             anywhere
INPUT_ZONES_SOURCE  all  --  anywhere             anywhere
INPUT_ZONES  all  --  anywhere             anywhere

REJECT     all  --  anywhere             anywhere             reject-with icmp-host-prohibited

mysql数据库

MariaDB [(none)]> SELECT User, Host FROM mysql.user WHERE Host <> 'localhost';

服务器在我的本地网络中，在不同的子网中。
内部防火墙设置为允许两个子网之间的连接，可以看到正在接受的流量。
你知道为什么它不允许我远程访问吗？
