1 Not Possible To Get Static Ip Of My Home/Remote Network From My ISP Because Of Lesser Competition between Broandband Companies Or They Main Reason Is Monoploy of Vendors.

2 Tunneling Not Possible Because The Maximum Connections Are Udp And Some Are Tcp, And The Reason For Not Choosing It Expensive For me. And the exchanges of files Over A T.B. In a Single Day. Also there is very less Providers who Supports tcp and Udp Tunneling.

3 Vpn Is Not Possible Because It requires machine on both Side of network And in my case i only have a router and a nas in one side and in others only A server,Router and a DVR.
