I have a standard master-slave replication for MariaDB to sync one database (master) to multiple slaves. One of the slaves lives behind a proxy, so I need to proxy the replication request to the proxy and from the proxy to the master. The proxy only supports port 80 or 443.

Can I use the proxy_protocol_networks parameter to proxy the requests? Can I proxy replications requests?

Example:

master: 192.168.1.1:3306

slave: 172.16.1.20:3307

  mysqld.cnf: proxy_protocol_networks= "172.16.1.1"

proxy: 172.16.1.1

slave:3307 ---> proxy:80/443 ----> master:3306
