Any help would be appreciated Thanks. Hi, I believe that we've finally found the issue. This article helped a lot: Here are four important things to remember when configuring the reverse proxy: 1. SSL decryption and re-encryption – Ability to install a public trusted certificate to the reverse proxy virtual IP service for the required URLs for decryption of packets on the public side, read and interpret the packet HTTP header to determine the correct back end service to send the request on to, and then re-encrypt the packet on the private side and send to the front end server. Symmetric routing must be configured. Iso reader for mac. That means that the outgoing packet from the front end must traverse the same route the incoming packet arrived on, i.e. In through the reverse proxy and back out of the reverse proxy. This is more of a networking requirement than a reverse proxy requirement per-say. The use of web proxy servers is not supported as it can cause asymmetric routing. If a web proxy server is in use, then all external urls for the Skype for Business deployment from all machines must bypass the web proxy server. Any form of content caching on the reverse proxy must be disabled. Caching is not supported.
