ISPConfig 3 replication and Stunnel

[stefanm]

Hi Everyone,

I am currently planing a small HA setup with two servers and ISPConfig 3 running. In contrast to the sample cluster setup in the manual, I'd like to route the database part of the replication through stunnel and use master-master replication. As I understand the manual, there is only one common setting for a ISPconfig slave server that is used both for database connections (using the standard port 3306) and the remote API. However for the stunnel I would need to configure ISPConfig to use localhost and a different port for database replication.

Can anybody give me a hint where I might change this in the ISPConfig source? Had a quick glance at the sources, but couldn't find a suitable place.
Perhaps Till or Falko?

Many thanks for your help.
