I'm trying to find out the port number of my computer to which my ISP actually connects & provides the internet service, given my ADSL modem is operating in Bridge Mode instead of PPPoE. I initially wanted to find out others users' port numbers, but I thought first I'd find out my own.
I'm on a windows machine, so I used the command netstat -a -b -n but could not figure out the port id. I suppose if there IS such a port number, there must be some sort of internal port forwarding being done. So then how do I find out my port id?
Edit: Basically my question is, How does the ISP send data packets to a computer..I ask this since I had figured out a way to impersonate someone using his MAC address and session id (my ISP is BSNL). So there could also be a way of hijacking someone's connection & breaking into his system. That depends a lot on how ISPs actually send data to different clients.
