Hi there, I know there is some of you already know this trick but most of you doesn't.
In this Tutorial I'll teach you how to appear invisible in your chat

I remind you that this tutorial is not going to change or modify the client.
Be sure to
ENABLE your firewall
Steps:
1) Open cmd.exe as Administrator
2)
If you are
NA North type:
netsh advfirewall firewall add rule name="lolchat" dir=out remoteip=216.133.234.21 protocol=TCP action=block
If you are
EUW type:
netsh advfirewall firewall add rule name="lolchat" dir=out remoteip=66.150.148.129 protocol=TCP action=block
If you are
EUNE (EU Nordic/East) type:
netsh advfirewall firewall add rule name="lolchat" dir=out remoteip=66.150.148.21 protocol=TCP action=block
3) Wait a few seconds and you are now offline!
How to get back online:
1) Open cmd.exe as Administartor
2) netsh advfirewall firewall delete rule name="lolchat"
3) Welcome back!
FAQ:
Why this doesn't work for me ?
Probably you've entered the wrong string or your firewall is not enabled.
I'm in a different region, what should I do?
1) Go to your lol folder and navigate to \RADS\projects\lol_air_client_config_euw\releases\ 0.0.0.46\deploy
2) Open
lol.properties with a text editor
3) Find "
xmpp_server_url=" and copy the next url. In my case is chat.eu.lol.riotgames.com
4) Paste it in cmd.exe and do "ping YOUR_URL"
5) You will see "Pinging URL [IP]" Keep in mind the ip
6)Copy and paste the command and replace INSERT_IP_HERE with your IP
netsh advfirewall firewall add rule name="lolchat" dir=out remoteip=INSERT_IP_HERE protocol=TCP action=block
7) Done
I'v done everyting right but it doesn't work..
The IP might be changed and the solution for the different region works well.
