I do have a virtual lab currently setup with the intentions of accessing a web page externally. My Setup: 1 ARR server and 2 backened servers serving the page that I need access to. All 3 servers are running Server 2008 Enterprise with SP2 w/IIS 7. My problem: 502 proxy error I'm trying to access my site externally via https however, I receive: 502 - Web server received an invalid response while acting as a gateway or proxy server. There is a problem with the page you are looking for, and it cannot be displayed. When the Web server (while acting as a gateway or proxy) contacted the upstream content server, it received an invalid response from the content server. If I change the NAT setting in my router to point directly to one of the backened servers, I get to the page just fine. The issue is when trying to access from the ARR server. I do have a rewrite rule configured that points directly to my farm. I've also checked inside the monitoring and management console and I am seeing that I'm hitting the page from outside but they're only failed requests. I'm thinking this might be security related as I did see this in the failed request logs: Trigger Status: 502.3 Module Set Response Error Status - ApplicationRequestRouting *Bad Gateway* Set Response
