Smoothwall proxy / HTTPS issue
We have a Smoothwall 3 proxy on our BYOD network. It is transparently filtering web access. We have found that it will not pass HTTPS / 443 traffic on BYOD machines. If you go in to the browser on the machine and explicitly enter the proxy in Connections > LAN Settings, you can access HTTPS sites. Remove this entry, and have it work 'transparently', and HTTPS stops. There are no errors or block pages displayed on the BYOD device, it just sits there and eventually times out. Any ideas as to why this is?
