sharepoint 2019 Intranet access from outside by external users

Question

The requirement is to access Sharepoint 2019 Intranet from outside by external users. Using Application Proxy Connector, Azure AD users can access from outside the network without publishing to DMZ Zone.

1) Is it possible to use FBA with Application proxy connector ?
2) Is there any license required for this ?

Answer 1

Hello,

I didn't use it for SharePoint but Application proxy and form based authentication can be use together (I used it to publish OWA for an Exchange onpremise)
The license requirement will be for application proxy which is Azure AD P1 minimum and based on this article for every user accessing the application via the application proxy.
For guest user the license requirement is a little bit different because it is based on a MAU (Monthly Active Users) which means your first 50000 will be free :
