As the title suggests, I'm trying to allow my friend access to the mySQL server/databases for my compiled TrinityCore server.
I've made his user and granted all the permissions to his account for the server but when he's trying to connect he gets an error:

Covered part is his IP

I've made sure that my port is being forwarded on 3306, but for some reason he's unable to get connected at all. The mySQL server is being hosted locally from my pc.
Any suggestions or help?

~Thanks in advance
