Hi All

I will try to make this as clear as possible.

Current setup:
  • 1 pc on a collge network (main work pc)
  • 1 pc on asdl (web testing pc)
  • KVM - Belkin Switch 2 to change between the above

Dream setup:

One imac capable of running both networks - with some kind of easy way of switching between them.

is the dream setup possible?

thanks in advance!

You can have multiple networks. And when you pull down the Network Preferences menu, toggle between the two with "Join Other Network"

Thanks for the replies...

the hard wired and wireless, seems like a the simplist, as long as the network staff buy me a wireless router too.

"Join Other Network" - is this part possible with if both networks where hard wired? if so how?

My understand is that whatever network you are hard-wired to, the Mac will recognize it and automatically connect you. You shouldn't have to manually switch back and forth.

For example, I plug into my work network, and get a DHCP address of 10.0.11.30. Then I go home and plug into my home network and get 192.168.1.11. It's seamless moving back and forth between locations.

You can have multiple network connections at the same time, regardless of whether the interfaces are hard-wired or wireless. The only caveat is that they need to be entirely separate networks. Not abiding by that means that at the least all of your packets will just run around on your machine and never get out and at the worst cause a loop that will prevent the entire network from functioning properly.

Now having satisfied the different network requirement, you can use the networks simultaneously, but you cannot, however, dictate which interface should be used to route traffic beyond the following:

If you specifically access a machine only available on one network, then the interface on the network you wish to contact will be used.

You will only have have default gateway (having two can cause problems), so if one interface is on a network that's just local and the other is on the Internet, obviously all of your Internet traffic will go out the interface that's on the Internet.

Now if both of your interfaces are connected to networks that have Internet access, then it's kinda hard to know which interface is being used when you access the Internet.

Hopefully that kinda describes the issues that might arise..if you could describe your network a little more, perhaps we can narrow down the things that might and might not work..
