[Query]Tunngle and Alliance broadband compatibility??

Dear All,

I have a query reg Tunngle and Alliance broadband.

Request you to please check the below post-
Play with friend not possible - Tunngle Communit

My userid there is onlytanmoy- same as here.

Any one from Kolkata using Alliance broadband can confirm if it is fine at their end or not? Do we need to call up Alliance requesting to open the port?

Thanks,
Tanmoy.
