I was wondering if anyone has seen this issue. I am not able to HTTPS into my NAC Servers but I am still able to manage them via my NAC Managers. What would cause this?
Yeah, that won't work. All traffic for the Managed subnets is sent out the untrusted interface by default and since your client is on the trusted side, it would never reach it.
The network you're trying to access your CASs from, is that network part of the CASs Managed Subnets?
