Here is something that raised my eyebrow.
At my office i have a Linux server for our company site. For us to access our webmail on the exchange server i have made an reverse proxy on our apache server.
So in general, the URL "www.pemel.se/exchange" reverse proxies to "mailserver.local.net/exchange".
When using the new beta, i can nicely connect to "www.pemel.se", but when i connect to "www.pemel.se/exchange" proxy breaks connection and i got a site not found. Disabling the web proxy lets me connect to the webmail again.
I have tried with and without content blocking and intrusion protection with the same result, this clearly looks as a proxy problem.
And it works flawlessy with the "ordinary" astaro version with squid.
