If your license will accept it, drag and drop the NPK found on the download page into the File window of Winbox. Then reboot.
what is NPK,im begginer in this job,can you exactly explain me how to do this, i think it should be a script to make this alert!
Thank youu.. 
i think you dont know exactly what i asked to you!however do something and tell me how to do this..
The only way to do this that I can think of is a redirect. This would redirect their port 80 traffic to a webserver with the message, The issue is thats kinda perm until the rule is disabled.
one thing I guess you could do is to have a script that monitors the rule and once the count gets above say 10 packets or something, then disable. Guess that would work, but sounds like more work than the outcome is .
We just disable their internet until they pay.
Hello. Do you just want to warn your customer who haven’t paid? I make one rule to them, they must pay in advance.
Or, if you want to send message via your PC, and if you’re using windows as your operating system, from the command prompt type msg … (for complete structure of this command, try to find the help in your windows os.)
I hope it would help.
hello djohan,you’re advice helped so much to me, i just wanna to warn my costumer who havent paid?Like this..
for example the client with xxx.xx.xx.x ip address havent paid, and i want to sent to their computers you have to pay…
Thank youu..

WIth repsSEct AlterNatVi
I typically redirect them to a webserver, not the MT. It would be a internal IP just for this webapge. I also modify the 404 error page in the webserver to be this. However, once they get this message, they can’t go anywhere on the net. They HAVE to contact me to pay. I do this in the morning so that they can contact someone ASAP.
That is the only way i have done it. This is just a simple, redirect port 80 to your webserver IP. Thats it.
ok my friend, i like this metod, but if you can tell me how to do this, maybe its simple for you but for me no,so tell me all procedure..how to redirect to webserveru, how tro modifi the 404 …etc,Thank you..or you i can give my email address ylberi_boy@januzaj.com..and talk about thiss..Bye
I can’t tell you how to change all that in yoru webserver and such. That all depends on your webserver. IIS its simple, just find the 404 error file and change it. Thats it.
man if you know i use Mikrotk OS, and i dont know where i can find 404 error Text ad edit it, so tell me …fo here and edit this text and …
404 error messages are given by the webservers, not RouterOS. this question is out of topic.
Actually you don’t need to modify the 404 page at all as Dennis suggested, it’s not necessary.
What you need is to redirect non-paying customer to an external webserver which has the message “please pay” and that’s all. One DST-NAT rule will do this for you. please read the manual for details.
