[SOLVED]How is it that you can kick?

I've always wondered about how you can kick people from MW2 and like block them from connecting to you w/o using admin tool. I heard alot about if like you go into the internet browser via (shift + tab) and you put in your 127.0.0.0 address or something that a list of the players would show up.

And that you'd be able to like kick/ban them from connecting to you, how can you do that? If it's possible and or how else can you do that?

kicking: have console, type in status: get the number of the player u want and then write clientkick(number)

Banning: i think u need a .gsc script for that, i have no ide. Maybe search it on google?

console: tempbanuser "name" (maybe works with tempbanclient)
