I have an iPad running iOS 8.1.2. I have added a manual proxy to the Wi-Fi connection but it seems that only the HTTP (port 80) and HTTPS (port 443) traffic is going through the proxy. Is it possible to pass all traffic through the proxy?
The Proxy you add is a http proxy. Port is not the point. In the other word, other protocol except http traffic will not going through this proxy. for example Facebook App using SPDY protocol so this app "bypass" your proxy
