Once you know your public IP (as suggested by using What's my IP
service), from an IP outside of your local setup (WAN preferred) do
"telnet <IP> port#.  e.g. telnet aaa.bbb.ccc.ddd 22   (this works for
any TCP protocol service).

You know the ports that you have opened - if the connection times out
(or rejected), then Airtel is indeed blocking incoming ports.  On
consumer services they probably do not want you to run servers behind
their modem and are blocking termination to some of the popular
services.

My dus paise.
