    I recently subscribed to a 50 mbps connection with YouBroadband. YouBroadband installed an Alphion router to provide me with a WAN connection. I am using a TP-Link router to share the connection.
    My problem is this:
    I am trying to set up a simple server and expose it on the internet, for learning and development purposes. But it seems that all incoming connections are blocked. I checked on my external IP using yougetsignal.com/tools/open-ports. The same issue exists when I try to play some games online. The server cannot send me a request.
    I set up port port forwarding rules on my TP-Link router, but that did not help. TP-Link's WAN IP address is a local address 100.72.X.X.
    It seems that I am stuck in a double NAT problem where I have no access to the NAT routers. When I did a tracert, it looked like even a triple NAT or higher.
    YouBroadband Customer Care is of no help. The "Technical Consultant" doesn't even know what a NAT or port forwading is?
    Does this problem exist with all broadband providers?
    Is there a broadband provider in south bangalore that provides suitable service for what I am trying to do.

    Can you access your alphion router?If yes then add your tplink router to alphion DMZ & in turn add your pc to tplink DMZ & see what happens.

    The alphion router is not using a WAN interface. The router does not allow a DMZ unless there is a WAN interface enabled. It seems to be using some optical fibre interface.
