Bridge RouterBoard, using it as a switch

RouterOS Beginner Basics
1

My knowledge of RouterOS is limited, so can someone please confirm that this configuration is good to use for a routerboard that i now just want to use as a switch. I will connect ether1 to my ISP where i get 5 external IP-addresses, the other ether port shall then give the inserted gear external IP’s.
Any changes i should make to the configuration for optimation?

There isn’t much to do, just bridge everything together and that’s it.

You might want to add some other tweaks, e.g. if you’d give the router (now switch) public address for management (probably not), you’d want firewall to control access. Stuff like that. But it’s not important for your main goal.

Don’t forget to disable the DHCP server. No need for it if you’ve just got a bridge. Unless you want it of course. But from your explanation you probably don’t want it.
