Configuring a new separate WAN

Hi Everyone,

I’m new here and also new at the work.
So, there is a Mikrotik already connected and working properly with 1 WAN and a few configured vlans.
And now for business purposes, I need to configure second WAN and a new server.
My question is: Is there a way to configure the new WAN on interface ether3 and the new server on interface ether4, so that they will working for only dedicated purposes and separately from others, and at that time only one of the vlans to have connection to the server?

Thank you in advance.

Of coutse you can. Use static source NAT one to one and connections marking.

Thanks for the quick reply. About the connection marking - is there any special things or configurations that i need to know, because I am starting to research about it.
