IANA (Internet Assigned Numbers Authority) is the association under the Internet Architecture Board (IAB) of the Internet Society that manages the designation of Internet Protocol delivers to Internet specialist organizations (ISPs). ICANN (a non-legislative association) has now accepted accountability for the errands previously performed by IANA. ISPs thusly assign IP delivers to little organizations, and organizations.

The IPv6 convention characterizes an arrangement of headers, including the fundamental IPv6 header and the IPv6 augmentation headers. The accompanying figure demonstrates the fields that show up in the IPv6 header and the request in which the fields show up.

Following is a small script on how you can redirect non-payment/ expired PPPoE users to a page where he can be informed that his/her account has been suspended due to non-payment.

Also described are things to do on the radius side

/ip pool add name=expiredpppoe ranges=10.10.10.2-10.10.10.254 /queue type set 0
 bfifo-limit=150000000 kind=bfifo /ip firewall address-list add address=1.1.1.1 
 list=radiusizin

Let’s enter the IP firewall mangle rule in the new terminal as follows.

Sometimes we want to prevent a harmful IP address.

Because the IP address we want to prevent can lead us to a malicious site or application.

Now we’ll explain how to do this step-by-step below.

First step; IP> Firewall> Address List>Name  following

Second step; IP> Firewall> General>forward  following

Third step; IP> Firewall> Advanced>Destion Address List  following

Last step; IP> Firewall> Action>drop  following

/ip firewall address-list
add address=1.1.1.1 list=Blacklist
add address=2.2.2.2 list=Blacklist
/ip firewall filter
add action=drop chain=forward comment=Blacklist dst-address-list=Blacklist

I hope it has been a useful article.

It is important for security to change the password from the Mikrotik default.

So what do we have to do for it?

We can change one from the winbox interface.
The other method can also be changed from the new terminal in winbox.

The user is first added from the system.

Then click Change password.

/password old-password="" new-password="NewPASSWORD" confirm-new-password="NewPASSWORD"

If we want the users we create to enter only from a specific IP address.

Things to do step by step;
We will shut down the DHCP Server, NAT, and Firewall on our ADSL Modem.
We will get the ADSL Connection mode from the ADSL Modem to BRIDGE MODE.
We will give IP to Local Interface on Mikrotik.
We will define the PPPoE Client for ADSL connection.
We’ll start the NAT definition and start sharing.

I cannot show here how to turn off DHCP Server, NAT, and Firewall on your ADSL Modem because all modems are different. You will find these settings in your own modem.
