How to expose a public sub-wiki outside VPN

Hello! This is related to the question I posted last Tuesday.

I am looking for recommendations/suggestions on how to expose a public sub-wiki outside of the VPN. Currently, our XWiki instance is only accessible with VPN and we would like some sub-wikis to be accessible publicly (no vpn, just simply opening the URL). Are there documentations in XWiki on how to do this?

Thanks in advance. :slight_smile:
