Mikrotik - Part One [ MOHAMED AHMED] « Null Byte

What is Mikrotik ?
Mikrotik is a Latvia company founded in 1996 to develop routers and wireless ISP systems.
It currently provides hardware and software for internet connectivity in most cities around the world.

Our experience using standard computers and completing routing systems allowed us in 1997 to create the RouterOS System that provides extensive stability, controls and flexibility for all types of interfaces and routing.

In 2002 we decided to make our own hardware, and RouterBOARD was born.

Then, Mikrotik is an operating system oriented to Networking being able to use pci / pci-e boards and hardware systems of the company.

-Within the Mikrotik equipment you will find:

Home-Office
Rackeable
Non Rackeable
Cloud Core Router
Wireless

-So far we started to know Mikrotik mtk, so it is usable in many areas and scenarios.
The characteristics of the OS are at the discretion of the administrator because they have:

Fully parameterizable firewall (IN / OUT / FORWARD)
Server and VPN Client
HotSpot / Captive Portal
Simple QoS and Quee Tree
Layer 3 algorithms (RIP / OSPF / BGP)
PppOe Servers and Clients
Possibility to bridge interfaces
Allows you to perform Load-Balancing
Scripting Consort
Allows you to schedule tasks
Ability to create White / Black list from DNS table

and many features fully configurable. It allows to implement multiple Vlans, to define a single Dhcp server with script of configuration (to avoid the impersonation of the server dhcp).

Home-Office (Rb450-Rb750) computers are those with decent hardware, 750Mhz processor, 128/256/512 Mb RAM, 4 to 6 10/100 or 10/100/1000 Ethernet interfaces.

Rack-mount and non-rackeable (Rb2011 - Rb3011) computers feature processors ranging from 512Mhz to Dual-Core 2.0Ghz, 256Mb RAM and up to 2Gb RAM, with SPF / Usb ports.

Cloud-Core devices are oriented to large ISPs (Internet Servers or Internet Service Providers) as the benefits are unlimited.

The main purpose of Wireless devices is to make PTP and MPTP connections also used in Home-Office environments.

All of them have quality tests, on the manufacturer's page you will find the information related to these equipments.

Personal experience

After an extensive time of investigation and training I happened to comment on the performance of some equipment.

Rb750 / Rb750Gr2 / Rb450 were used in home-office environments with up to 20 computers, about 50 rules in the firewall, with only one ISP, Quee Tree, Dhcp Servers.

In itself the performance is stable although in certain moments when all the equipment are connected and making consultations, the CPU reaches 100% something that is totally detrimental for the stability of the network because many connections must be reestablished the times of delay begin to be high.

Rb750Gr2 as core router, mainly with the functions of providing internet users and as a firewall, here with more than 300 users connected; in combination with a "Switch Layer 2 - Manageable" performance is stable and may be better.

Rb2011-UiAs here I found another segment of equipment with more powerful and more flexible hardware. Approximately 50 users, Quee Simple, QoS, Firewall (approximately 100 rules) in an environment where a DMZ and servers were only accessible from LAN.

Rb3011-UiAs-RM a router with exceptional performance, I get to work with a load balancing of 4 lines adsl and 4 lines with static ip for more than 200 simultaneous connections.

Considerations
At the time of purchase, the following issues must be addressed:

1) How many computers will you manage?
2) The internal network will be expanded
3) You need QoS - what layer and what protocols
4) Will use site-to-site VPN client-to-site
5) Will implement load balancing

In the next entry, you will begin to know the main features of an RB from the inside
