This issue is based upon my Telecom ISP,
I found a security hole in my Telec ISP to access internet for free, which is any connections any port that uses HTTP protocol is allowed for free. But other than HTTP services like, HTTPS, ICMP, P2P is blocked which left me over a situation that I can only use HTTP Proxies (Web Proxy & Normal Proxy) with any port for connecting to internet.
I can't connect to VPN as TCP & UDP is also Blocked. Tried to connect to VPN using HTTP Proxies (CONNECT) but it also fails as CONNECT method is based on SSL Protocol.
TCP VPN log:

Is ISP can block / filter my SSL connections using Web Filter?
Is there a way to bypass the filtering and use the Internet via any techniques like tunneling ?
Can I use the Blocked services like P2P through bypassing the filter?
Please provide me a solution! Thank you in Advance.
The problem is only on free mode, when i am using the paid internet all services are working with any throttling / filtering.
Some proxies usually not support the CONNECT protocol, so i checked them with Paid Services of same ISP it works very well & connects to VPN.
Tried downloading torrent with Bittorrent (by HTTP proxy) is not connecting in free mode but works in paid mode.
