[tec13]

Hi everybody, i want ban some users by ip range, but is there a problem:
it is what i do:
in Tea*Speak 3.5.6 client > Tools > Ban List > Add:

IP: 5\.126\.\d{1,3}\.\d{1,3}
Name: NOTHING(empty, no value)
Interpreter IP/Name as: Regular Expression
Unique ID: NOTHING(empty, no value)
myTeamSpeak ID: NOTHING(empty, no value)
Reason: NOTHING(empty, no value)
Duration: permanent

when i add a ban with this parameters just happened nothing, can someone help me to how can i do range ip ban?
(i was test this parameters exactly in Tea*Speak server and its worked(user banned), but in teaspeak server it didn’t worked)

We do not give support related with third party clients.
Use yatqa or teaspeak client.
You can always use iptables.
