How to disable CRZ (get into an empty realm)

In this way,you can disable CRZ and do anything in a place where no one else (except those who also know this way in your server) in.
In other words, you can enter an independance (or isolated) realm
that is to say, the mobs, pets and rare elites will be there.


Tools:
no special tools needed.
i did it in windows 7, and ipv4(i think ipv4 is required)

Theory:
queue for a BG, alt+f4 for 5 minutes to let BG kick you out
Block the crz ip and logging in,then you will be "kicked" out to a non-crossrealm world
In easier words.
find ip of crz---queue for bg-- alt f4--block ip ,wait for 5mins --log in--done


Steps:
(Perhaps the steps are long,but they are easy. so be patient)
1.
log in your account, then go to a non-crossrealm zone.(e.g. Stormwind or Orgrimmar)

2.
win+R ,run cmd.exe

3.
enter netstat -n
(it will show you the ip addresses which are used by programmes)

4.
you will see many messages like this(the addresses are examples)
.....
TCP 192.168.123.123:12345 222.111.222.111:80 ESTABLISHED
NOTICE CAREFULLY ,"ESTABLISHED" , NOT "TIME_WAIT"
.....

the first ip address is your local address
the second is the receiver(number :80 is port number)

you should find all the receiver address at port 3724
when you are in Stormwind or Orgrimmar,there should be one or two ip at 3724
e.g.
111.122.133.250:3724
111.122.133.251:3724
you should notice that the first 3 parts are the same,because Stormwind is a non-crossrealm zone.
if the address is aaa****b.ccc.ddd
the aaa****b.ccc is your server address. (it will never change,only "ddd" changes)

now,keep the "aaa****b.ccc" of your realm

5.
go to the zone you want to disable CRZ

6.
netstat -n
again

if the "ccc" of two ip addresses at 3724 changes.
e.g.
first:
111.122.133.250:3724
111.122.133.251:3724
now:
111.122.133.244:3724
111.122.135.166:3724

it means you are transferred to another realm whose address is 111.122.135.xxx
you can go to step 7(don't forget to remember the changed ip)

There is a little chance that the third part(ccc) of the address doesn't change,
that is to say,players are transferred to your server,the zone "belongs" to your server,and you should try another zone or wait till the arrangement changes
it is common if your realm has a major population of your BG group

7.
queue for any BG
after you enter the BG,just alt+f4 (no special timing required)

8.
run "windows firewall"
click on Windows Firewall with Advanced Security in the left pane
ensure that the firewall is on
you can active them in"windows firewall properties"
(Domain Profile,Private Profile,Public Profile should be active)
right click on"inbound rules"--new-- custom--all--any--choose the remote ip address to block,add the range to cover the ip address you got in step 6
(the changed ip)
e.g.
if the changed ip was 111.122.135.222
you should enter a range to cover its fourth part ,but not too big
111.122.135.150 to 111.122.135.255 is proper
111.122.135.2 to 111.122.135.255 is improper
(don't include all from 1 to 255, or you'll be ported into an empty world)

do the same thing to"outbound rules"
(all the step 8 should be done after you have alt+f4ed)



9.
after you have logged out for at least 5 minutes and the crz ip has been blocked by "in-outbound rules"
log back to game
you should be kicked out of BG and get "deserter" debuff
you should receive repeating error messages in the chat frame
you should be in your "local" "ccc" server ip address (you can check it netstat -n)
"transfer aborted instance not found" should come again and again(once 60 seconds)
it's the most important sign of success
if it only occur 1 or 2 or 3 times ,you seem to be "placed" into a not blocked "ddd"
for example, you only blocked 111.122.135.250 to 111.122.135.255
the system will first try to place you into 250 but failed,then placed you to 251,also failed, finally it may place you into 153 , here comes 2 "transfer aborted instance not found" s but finally failed
on the other side,if you block 111.122.135.1 to 111.122.135.255 , i think at least 1 address is for special use ,like serverside check . it may not be "1", so 1 to 255 or ,may 50 to 255 may cause an empty zone.
my own range is 150 to 255
if you're sure that your server is not the"host" server ,you should netstat -n again to check which server on earth are you ported in,if it's the range that caused the problem,you should change it.



now you have disabled CRZ , and you can do anything in the zone(rares,pets, and nobody else)


After you leave the zone or relog, if you want to perform it again,you should disable the in-outbound rules and do all these above again
<don't forget disable the rules ,or you may meet network problems>

However some realms this won't work on, for example Argent Dawn eu didn't work for me.
