Features:

 

-         Mikrotik as a domain controller: we can use Mikrotik as a server, were clients connect to it by PPPOE protocol connection by using there own username and password given by the administrator.

This connection is secured and the physical address of each network card and username can be captured and saved in the Mikrotik itself and any trial of logging into the account using the username and the password but from another physical address is not allowed.

We can use Mikrotik to make a small ISP by this feature of by the Static IP method. All what we need is an internet source (gateway) passing to the Mikrotik server  and we can provide internet service for each customer providing him his own Queue, so if we take 1MBPS connection we can provide more than 20 clients at once giving a speed of 128 KBPS for each and at once (at the same time).

Also one of the Mikrotik features other than the ability to control the Queue of the connection provided to a client, that it provides each client a connection speed graph of his yearly, monthly, weekly, daily, and momentary usage of speed of upload and download speed, he can access it any time he wants by using his own link u can give after configuring the graph on the server. Also you are provided by the graph of the real connection consumed by your server. (A Bandwidth Monitor Graph) and it is accurate and real.

 

-         Using Static IP Connection: Also we can use all the features explained up but not by using the PPPOE protocol and username and password, but by using a Static IP connection, by providing each client with his own IP. Also physical address of the network card is kept and any connection from another physical address is not allowed.

 

-         Firewall: Mikrotik firewall is one of the highest security level firewalls available among servers, since it is a Unix Firewall, and it is the easiest to deal with among all other available firewalls.

You can use the Mikrotik Firewall in two ways:

     1st: Closing all the ports, and allow only the ports you would like to allow.

     2nd: Opening all the ports, and closing the ports you wouldn't like to allow.

     Available ports to prevent or to allow: Any port, also virus ports, worms, voice, cam … etc.

 

-         Web Proxy: Mikrotik web proxy is a perfect web proxy in which you can control your web access. You can prevent certain websites or prevent any downloaded extensions as: .exe, .zip, .ram, .bat … etc.

You can make the proxy a transparent proxy, in which any client whatever he use a proxy in his browser settings or not, he will pass the server's web proxy in both cases. You can enable the proxy, disable it, clear the cash … etc.

 

-         FTP: You can make your server accessed by ftp protocol, in where you can store files and documents, and give security privileges to certain users to access these data via ftp from anywhere in the network, or u can make it open to public usage (anonymous access).

 

-         Mikrotik as a Wireless Link:

 

Instruments Needed:

1-     Wireless PCI card 108MBPS (<30 $)

2-     2.4 GHZ Antenna.

 

We can use Mikrotik as a wireless link using frequency of more than 70 channels, starting from 2.3 (2317) channels and ending at 2.5 channels.

The benefit of using Mikrotik in wireless configuration is the ability to have a high quality connection for far distances reaching more than 75km. Up to 20km distance connection is available with low cost materials (<120$) and with ping time (<1ms), while from 20km up to 75 km and above cost about 750 $ and above.

When using Mikrotik as a wireless link, you get benefit at the same time from its other features as ftp, web proxy, PPPOE server and static IP server, as a router.

Mikrotik as a wireless link can be used as point to point wireless connection, or point to multipoint connection and you can hide your SSID of your link and give it security privileges, and always trust that using it as a wireless link is the cheapest among all other available solutions, and is the most effective and reliable among all them.

 

-         How Can We Control Mikrotik System?

We can do this by using several methods:

1-     HTTP Web Interface.

2-     Software (user) interface.

3-     Telnet.

4-     FTP

5-     Mac Address Telnet (and it is a unique feature special for Mikrotik).

 

-         Why We Choose Mikrotik?

We choose Mikrotik because of many reasons:

It is the cheapest solution, most reliable, effective, easy to deal with, and available solution. Its requirements are so simple:

1-     233MHZ CPU and above (Pentium II and above).

2-     64MB Ram and above.

3-     500MB Disk space hard disk and above.

4-     10-100MBPS PCI network card.

 

Depending on the above information, we can see that it is the cheapest requirements among other servers or operating systems from Microsoft or Linux, and not because it is cheap that means that it is not reliable or effective, at the contrary, it is the most reliable and effective solution among them.

It is easy to deal with, when there is many Mikrotik systems on your network, you can hide the system you want from another systems, and you can control one system from any point in the network even if it is not from the same range. (You can control 192.168.1.x from 195.162.20.x).
