There is an old issue in JIRA to track this (please vote):
https://jira.mariadb.org/browse/MDEV-11159

If you want to give a shot to porting that to MariaDB, I'd love to have
this feature personally.

> As you may know, the proxy protocol [1,2] is a way to communicate
> a client's IP address to a backend server sitting behind a proxy
> front-end. It is the equivalent of the X-Forwarded-For HTTP
> header, but done at Layer 4.  This protocol was originally
> proposed by one of the HAProxy developers and its support is
> becoming more widespread. Percona, Amazon AWS, HAProxy, NGINX,
> and others.

> Mariadb's Jira shows an unassigned feature request for it, but

>
> Percona supports proxy protocol [4]. For the configuration part,
> Percona defines a global variable that gives the IP address of
> the proxy front-ends that are authorized to send a proxy protocol
> header.

> Percona's handler code for the proxy protocol (minus the global

> insertion point. Percona's software license seems to be permisive
