hi I recently got a brand new airtel connection in bangalore, Malleshwaram. However when I was testing it, I found I could not connect to irc servers. The problem is port 6667 is blocked, but not 6668. I asked the guy and he asked me to contact customer care. I contacted them and they said that they have a bunch of blocked ports for "security reasons", but they cannot reveal which ports are blocked. The local engineer also said something about how all these ports are blocked by most major ISPs (except BSNL), since they all get their connection from some big Asian backbone and this is some sort of policy. I wonder if anyone knows anything more about this, or can add to this?IRC is a very old and fairly well used protocol. So its very strange that that port is blocked. Coincidentally, Bittorrent uses port 6667 in the range of default ports.
