I just recently switched to airtel BB due to BSNL not hurrying up and giving me my connection. That one will be canceled. I have a question. Does Airtel block tcp/udp ports at the server side? I'm trying to forward ports using the NAT function, but when testing it out, it does not show that it's port forwarded? How can I fix this? Thanks guys. Oh and uh.. I have connected my modem to my wireless router, running it wireless at the moment.
