Hi,
I'm on the newer side of networking, but I have a friend who shares his internet via a Ubiquiti product and currently we have a switch after his modem then his router. His router needs to get replaced and I've been using Mikrotik for a few years and love them. Is there a way to connect his Modem to the Mikrotik and then have one port specifically pass through a public IP(DHCP) while the router has a different public IP and still acts as a router on the rest of the ports. If that is a possibility could someone let me know what kind of process this is so I can research how to make this work. I am just not sure how to describe this well enough to search it myself.
Thank you,
Chris
