I was facing a weird problem on the LAN today.
If i have some TCP connection open, then that would work perfectly fine, but the rest won't. For example, if I am logged into G-Chat (the chat in the gmail), then the chat would continue to work perfectly as it would under normal internet connection. However, if I tried to open even google.com and/or open gmail, the connection wont establish as if my net is down.
To confirm my suspicion, I started streaming an online video (when I could), the same thing happened in between. The video continued to buffer perfectly with the same good speed as if my net is perfectly fine, but none of the other sites opened up.
Since the socket or TCP connection was already established, I believe that once a connection is established, it works but the rest of packets are being "stolen" or redirected to one or some particular addresses in the LAN.
So my question is what activity and/or software is capable of performing such a task and how does it work exactly?
Also, is there a way to stop it?
Any help is much appreciated.
