I have running a WAP (Server 2019) and an IIS (10.0). On IIS, a website is running, https://te.contoso.com/.
A subfolder (te.contoso.com/subfolder) is protected by one-to-one client certificate authentication.
This is working fine, as long I am inside the network. As soon I go via WAP to the protected subfolder, I get an error 403 from IIS (every time with the same device).
WAP is configured as pass through (https://te.contoso.com to https://te.contoso.com). https://te.contoso.com itself is working from external as well.
Only https://te.contoso.com/subfolder displays 403.
How do I have to configure WAP or is this not possible like this?
Seems like WAP is not delivering the client certificate IIS.
Thanks for your help!
