Which application path to use for Windows IIS in Advanced Firewall Rules?
cn flag

I'd like to unblock my IIS ASP.NET 4.5 webservice for public access.

In Windows 10 Advanced Firewall Rules I added an inbound rule to accept all incoming requests for my webservice's port (e.g. 8001). That's working fine with "allow all programs".

However, I'd like to further restrict this rule to only work for IIS.

IIS ARR - Route single request to multiple servers/sites

We have a unique situation with a vendor in which they only allow 1 address for PRD traffic and 1 for Non-PRD traffic. Internally, we need to be able to test in 2 environments (call them TST1 and TST2).
