I'm a newbie at both networking and mikrotik, i am having some issues forcing my router on the inside getting dchp from my internet provider, here's my setup.
Incoming Fiber (ISP only gives 1 ip address per household) <-> Mikrotik rb260gsp SFP fiber port (WAN)
Mikrotik Port #1 <-> Ubiquiti Edge Router (Edgerouter looks for dhcp on eth1 which is connected to mikrotik port #1)
Everyting works fine if i only have these 2 devices connected... But if i connect the rest of my devices to port #2, 3, 4, 5 and reboot the Mikrotik switch, it's random which device gets the ip from the dhcp from the isp, and since they only give 1 ip the other devices get locked out.
My question is basically, how to i force the mikrotik switch to only give ip to the device that is connected to port #1 and the other ports are internal switching only?
