Dissecting Details MikroTik Router Default Configuration

 At the moment we first MikroTik router settings that are new, we sometimes difficult to remote in ether1, or when we've managed remote router, in the router configuration seen already there are not so familiar. This is not because malfuction MiktoTik router, but because of the default configuration. For some people, it's easier than the initial configuration of a router when no configuration at all. But for those who are still learning MiktoTik settings, the default configuration will be very helpful. We will try to describe more details about the default configuration.

router has a default configuration will typically show that there is a default configuration information after login console or display a dialog box when the remote using Winbox. Examples of the dialog box when the remote with Winbox:

This dialog box displays 3 options. "Remove Configuration" will remove the default configuration so that the router will be clean, without any configuration at all. The option "Show Script" will display the default configuration script. And the option "OK" to install the default configuration into the router.

Each type of router has a different configuration defaults depending on the condition of the device hardware. Scripts default router configuration can be displayed with the command / system default-configuration print

Now we try to describe in general the default configuration.

Ethernet

Default configuration will give the name of the user interface that is intended to be easier to determine which interface cable will be installed.

• Ether 1 will be named ether1-gateway assuming the user will install the cable that connects to the Internet to ether1.
• Ether 2, will be named etherx-master-local.
• Ether until the ether last 3 will be named ether3-slave-local. At this interface, setting master-port will be redirected to ether2 that are in the same network segment with ether2 interface.

Users can connect to the local network ether2, ether3, and so on except ether1. Local network segment should also be in the same segment.

IP Address

The default configuration will put up the IP address for the interface connected to the local network with the IP address 192.168.88.1/24. So that would use the local network segment 192.168.88.0/24 network.

But these hi not apply to products that have 1 ethernet interface, series RB411, RB433 series, series RB435, RB800 series, CCR series and RB1000 series. Fixed IP address on ether1 interface installed.

DHCP

DHCP Server will diajalankan by default in the configuration interface connected to the local network. Client quite connect to the ethernet interface in addition to ether1, it will automatically get the ip address.

The default configuration is also running DHCP Client service on ether1 interface is assumed to be connected to the internet. ISP usually provides the IP address dynamically so that the client does not need kesulitasn setting the IP address, gateway, dns, etc.. If the ISP or modem automatically assigns ip address, then simply connect the cable from the Internet / ISP to ether1 MikroTik router, the router was able to get an IP address and connected to the internet.

Wireless

For devices that have embedded wireless interface, there is also the default configuration for multiple settings depending on the condition of the router hardware.

• Mode, which has a license for the device leve 4 and above, by default will use the mode "AP Bridge", while for a router that has a level 3 license using station mode.
• Band, if the router only support at 2GHz and support MIMO, it will use the band "2Ghz-b/g/n" and routers only support 5GHz band and MIMO will use "-5GHz a / n".
• Frequency, on the support Roiter 2GHz will use the 2412 frequency. And the router will use the 5GHz frequency support 5300.
• Chain, for which the router supports dual chain, will use the default settings enable the chain 0.1. and for routers that are still single chain, will only use the chain 0.
• Security Profile, the default config will create a security profile with the serial number of the router as WPA and WPA2 Key.
• SSID, will be determined based on the wireless interface mac-address. usually will set the SSID "MikroTik-[Six Digit Last MAC-address]"

In addition to providing some of the above settings, the wireless interface will be bridged with ethernet interface so that the local wireless networks are in the same segment of the cable network.

For devices with additional wireless interface installed in MiniPCI port will be disabled.

Firewall
There are some firewall rules to be made by the default security configuration for the router and the router to save resources by conducting drop packets that are not needed. Here's the default firewall rule configuration:

/ Ip firewall filter add chain = input action = accept protocol = icmp comment = "default configuration" filter add chain = input action = accept connection-state = established in-interface = ether1-gateway comment = "default configuration" filter add chain = input action = accept connection-state = related in-interface = ether1-gateway comment = "default configuration" filter add chain = input action = drop in-interface = ether1-gateway comment = "default configuration" nat add chain = srcnat out-interface = ether1-gateway action = masquerade comment = "default configuration"

The first rule in the firewall will menijinkan bound ICMP connection to the router. The second rule allows connections that already have established status heading into the router. The third rule allows connections that already have a status that is also related to the router. The fourth rule will do drop any incoming connection to the router through interface ether1-gateway. And the last rule is a NAT rule that allows a client to borrow under the ip router router to be connected to the Internet.

DNS

Static DNS configuration is created by default with the dns name "router" and the IP address 192.168.88.1. This means that the router is also running as a DNS server. If we open our browser and then type in the address bar with the address of the addressee http://router by the browser is 192.168.88.1 and the display will show a web-base MikroTik router.

Tips

The default configuration can be edited or removed as needed. If it turns out the default configuration makes it difficult or even confusion in setting up the features we need, we can eliminate a number of ways.

First, the remote router must necessarily first, ktika dialog box appears informing about the default configuration as the first picture in this article, select the option "Remove Configuration". Or if you find that the default configuration is installed, can be removed by a reset or netinstall.

So, from now on do not be confused or even panic when the remote router could not be the first time.
