The Opera Mini browser contains a Turbo mode, which makes use of proxy technology to speed up browsing. Turbo mode enables a proxy within the Opera Mini browser which bypasses your proxy server and so bypasses the Smoothwall web filter. It can operate in HTTP mode or via port 1080.
- Block the Web Proxies category (the What) in Guardian, see our help topic, Creating web filter policies.
- Outbound TCP port
1080is blocked on your firewall's outgoing port rules.
