Can a unmanaged switch route different IPs

Ximerous · Dec 1, 2015

So say my ISP provides me with multiple public IPs and I have say three servers, each connecting to a different public IP. Would a unmanaged switch be able to direct the traffic correctly?

No. An unmanaged switch is a layer 2 device (MAC). It doesn't know about IP (layer 3).

So would a managed switch do what I need, or if not all what should I look for in one to do this.

Maybe. Some managed switches are full layer 3 devices. Cisco switches can be full layer 3 devices with routing. I think you really want a commercial firewall/router like a Zyxel UG100 or similar.

I only want like 5-8 ports, what would you recommend for that, since switches can get expensive quickly.

I have a different answer, since a dumb switch is layer2 only, it should pass EVERYTHING right?

I have a more pressing question, what kind of router(s) are you planing of using?

Am assuming you are NOT attaching those pubic IP directly to your servers, without a firewall (NAT) in between? So once NATed, in your LAN, all 3 servers will have private IP don't they, and perhaps on the same subnet? or are you purposely keeping them on separate subnets?

I just have a EA6900 from Linksys but I'll get a new one if I need to.

Update to jsmiths update: Yea I'll have firewalls and such, I just need separate public IPs for them.
Also the servers aren't all setup yet.
