Generic Forward Proxy with Websense Filtering iApp

Thank you so much for sharing this iApp. It is showing promise to provide a proxy for a special situation here where we need to provide a method for Skype clients to 'get around' our IronPort (Cisco WSA) web proxy. It has tested well as a socks5 proxy for my web browsers but it doesn't seem to click in when the skype client is configured for socks5. I brought up the HTTP proxy and that is showing much more promise and we will be testing further today. A few questions as perhaps someone else has gone down this path before... 1. Anyone had experience using the socks5 proxy for Skype or similar video clients? 2. Is there any plans to provide authentication for the proxy? It would help. I may tag source IP or may setup a 'side' authentication page to authenticate/validate the client IP to use the proxy but it would be nice if the authentication method within the proxy could be used. 3. Plans for adding UDP for socks5? Thanks again.
