Allowing Connections From Remote Clients

[Carlos Mennens]

I am trying to connect to MySQL server [192.168.0.100] from my PC
[10.1.10.222] using MySQL Workbench and when I test the connection, I
get the following error:

"Host 'tuna.iamghost.com' is not allowed to connect to this MySQL server."

Can someone please tell me what I need to do so I can allow remote
connections to the database from the MySQL workbench application? I
have access to MySQL via CLI.

Thank you!
