So here is how to configure it

> warning While multisite is supported in the Discourse application, this is an advanced sysadmin setup. If you don’t know what you’re doing, do not set up multisite.

Then there is this topic  
[https://meta.discourse.org/t/can-multisite-instances-communicate-with-one-another/8984](https://meta.discourse.org/t/can-multisite-instances-communicate-with-one-another/8984)
