RouterOS allows slight system customization with the help of a branding package. This is a special system package, which you can generate from within your mikrotik.com account, in the account section "Branding maker". The resulting file will have a .dpk extension and can be installed by all the same means as an .npk package. The generated package can be installed in any RouterOS version. To install the package in a device you simply need to upload it and reboot the router, you can also use Netinstall tool for the same effect.
This is the text logo shown, when logging into the command line interface, i.e. Telnet, SSH, Winbox Terminal. The ASCII logo you can create right there in the browser, or copy from any other plaintext editor. Make sure it is not wider than the form in the branding maker page, or your logo will be distorted.
You can customize the default RouterOS information page, which shows up, when accessing the router IP address, and a password is set on the device. When making the HTML file, you can use a these variables:
"Router name": this is the Identity value in RouterOS, it can only be one word, don't use spaces or special characters there.
"LCD logo": this will be displayed on devices equipped with LCD screen. Requirements for logo: no more than 160px width and no more than 72px height. CCR series have white (0xffffff) background, 2011 series have black (0x000000) background.
"Default configuration": Note that when using the default configuration file, configuration is appended when simply installing the package, but after using system reset, only the configuration in your file will be used, all other standard default config will not be used during reset. The file must be a text/rsc file with one RouterOS command per line. You can use a export file from the console as a starting point, but we recommend only leaving the exact commands you want to be run. This configuration will be kept even after RouterOS reset.
"Skins": For skins, a file default.json must be uploaded into "skins" directory.
"Custom files": RouterOS 6.48.3 and above also supports uploading of custom files, they will be simply copied into a folder named "branding" and will be accessible from within RouterOS.
