remotely access ispconfig mysql

hello all,
i'm new to ispconfig, i want to access mysql remotely.
created account, gave privileges, i can login locally, but not remotely.

Code:

netstat -tap | grep mysqlf
tcp        0      0 0.0.0.0:mysql           0.0.0.0:*               LISTEN      11382/mysqld     

 

when i try to connect from another computer, stays still and timeouts after 2-3 minutes..

Code:

# ufw status
Status: inactive

Code:

# iptables -L
