Before you do anything else with the MikroTik RouterBOARD RB751G-2HnD, or any other device running RouterOS with a default configuration I guess, you should configure the device with some bare minumum security features.
Set a password
The first thing to do is changing the password for the default user “admin”. When you are logged in, you can do this two ways (at least), either by setting it directly:
[admin@MikroTik] > user set admin password=somegoodpassword
Or by using the “password” utility to set the password interactively:
[admin@MikroTik] > password old password: ******** new password: ******** retype new password: ********
