[LIH] how to bypass ISP blocking NAT?

Hi friends,

I have a internet connection from Nivyah Broadband, Mumbai. I have been using  it for long now, and sharing it using a netgear router. Unfortunately, around 1 month back, I found that I am not able to use the internet. I did a traceroute, it showed no problem, but I was still not able to browse. I tried using other service provider on the same settings i.e. changing the access-concentrator details etc. it works fine.

Switched back to Nivyah and again the same result. I am not able to browse or in otherwords not able to use internet. 

Please can somebody guide me, how can I bypass the ISP blocking me from using internet from a router?

Also, I would like to know, how would an ISP come to know that I am sharing my net connection. 

I tried googling it, but was not able to find any satisfying document on same, on my own. If there is anything on same I would definitely like to read on it. Please assist.

Thank you 

Ratnakar Koli
