I have 2 servers:
SP01.test.local - Sharepoint 2013 foundation server
WEBAPP1.test.local - Office WebApp 2013 server
These two are linked together via WOPI so that SharePoint users can use the WebApp's in Sharepoint. This works fine.
By default, traffic between the client and the WebApp's (opened via Sharepoint) are directly between those two.
What I want is that the client only communicates with the Sharepoint servers, and that WebApp is routed/proxied through the sharepoint server.
So, for external access, only port 80 and 443 have to be opened/forwarded to the SharePoint server and that all traffic concerning between the client and the Office WebApp is router/proxied through SP01.
Is this possible, or does a client always have to communicate directly with the Webapp server?
