One example of how this would help is the following. If there are times when there's a need for security, to isolate the Mac from one of the networks, that's managed with the geared popup at the bottom of the Network window. In this case, a second IPv6 network is being used for testing. The Mac Pro can access everything on both of those networks at the same time, and devices on those networks can see the Mac Pro.įor example, here's what the Mac's System Preferences > Network might look like for port #1 (called Ethernet).Īnd here's what it might look like, in parallel, for port #2 (called Ethernet 2). I've chosen to use two of the most popular private (non-routable) IP address schemes, 10.x.x.x and .x, in this example. (Dual Networks) In this case, the Mac Pro is connected to two separate networks, both on the Internet, and each Ethernet port has its own IP address. Now, let's look at the bottom half of Figure #1 above. Or two small, co-located companies may be sharing resources. For example, one might be a production and the other an experimental network (or a back up). However, it may happen that a home or, more often, a small business may have two separate networks. Those scenarios are generally reflected in the top half of Figure #1 shown below, using just one Ethernet port on a Mac Pro. Cable Modem > Wireless Router with ports > Macs, iPads etc.


Unlike all other Macs, the Mac Pro line has two Ethernet ports.
