Just noticed that our test environment AD FS certificate will expire soon so I needed to change it. This blog post will show you needed steps to change certificate to AD FS and also WAP.
in earlier blog which can be found from HERE we created DMZ virtual network and needed subnets. We also already allowed HTTPS 443 connection from DMZ network (DMZ Subnet) to production network (Azure VMNet 01) so we are able to configure AD FS and WAP (Web Application Proxy). Next we will setup the AD FS part.
