Change external IP

Hello ladies and gentlemen.I need some help if possible.I want to change external IP for my virtual machine which its connection is bridged.I have done some research ,but i am quite a newbie to understand.If someone has the patience to explain i would appreciate.

Thankyou

Do you have this virtual machine set to dynamic ip? if so, then you need to change de value on ip-addresses set on your mikrotik. If you have a range of IP’s on your mikrotik (assuming you have one) set to the interface that your physical machine is connected, then you need to change the ip on the actual physical pc (that is bridged to the virtual) and you should be set.
