Network

Bandwidth divides Internet is simply based interface using Mikrotik. This time we will discuss in this article. Before I proceed, I suggest reading the previous article on How to Limit (Limit) Bandwidth Mikrotik Mikrotik with Simple Queue.

Okay, we just started. So this time we will make the distribution of bandwidth is simply based on the interface used. For more details, please see the following network topology:

Internet bandwidth I use is as follows:

Manage and restrict the bandwidth usage of the Internet is an important thing when our internet connection is limited, for example, quotas limited bandwidth of the ISP. We need to limit the quota of bandwidth each user is connected to the Mikrotik Router. On Mikrotik Router itself is already available features that can restrict (limit) bandwidth is Queue. There are two kinds of the queue on Mikrotik

1-Simple Queue: the easiest way to perform bandwidth management applied to small to the medium-scale network to set upload and download bandwidth usage for each user.

What it Romon? Understanding Romon Mikrotik

Romon stands for Router Management Overlay Network which is a new feature from version RouterOS Mikrotik at 6.28. Romon this feature may be unfamiliar to you because it is only available in RouterOS and WinBox new version. Well, to find out more about what it Romon Mikrotik, let’s discuss in this article.

Understanding Romon

What it Romon? Romon (Router Management Overlay Network) is a proprietary protocol Mikrotik (protocol is only supported on Mikrotik), which can make a connection layer2 safe (secure) to the device either through connections MikroTik “Physical” (Ethernet) or Layer 2 Tunnel. In addition, Romon also has the following features:

Perform an upgrade or update to the latest version RouterOS version is to note the Mikrotik. With the upgrade version of RouterOS then Mikrotik you will get new features as well. For example for the Mikrotik RouterOS version 5.2 and have not installed the user manager it should be upgraded to the latest version (eg 5:24) first can let the user Install package manager from the download page Mikrotik.

Okay, this time Mikrotiknetworking will discuss how to upgrade the version Mikrotik RouterOS with a contrived example RB751U-2HnD of RouterOS RouterOS 5.2 to 5:24. Actually, there is a newer version that is RouterOS 6.0RC12 but since version 6 is not yet final version so the safe use version 5:24 was yes;)

It should be protected from attacks such as IP Flooding or DDOS, which in fact is the worst of the types of attacks and still has no complete solution to prevent over the world. In this case, servers on the network must hide the outside world. Hiding ICMP packets will be a starting point for this, which should already be hidden for critical servers.

This configuration can be done through firewalls above, but the method we will talk about here is to show that this process can be done in the Linux kernel module, there are many parameters like this in Linux kernel modules and these parameters are examined separately for each process and these parameters are examined individually. It must be configured. The kernel parameter for this change is the module “net.ipv4.icmp_echo_ignore_all. Now we should take a look at how to do these operations, but let’s take a look at what the default parameter of this variable is and see if it is “0”.
