MacOS – If I am a member of multiple networks, how can I force the Mac to connect to the Internet through one specific network

internet-sharingmacosNetworkthunderbolt

I have a Macbook and a Thunderbolt display. The Thunderbolt display is connected to a network with a very tight firewall. I also have a WiFi connection that is always connected at this location. The WiFi firewall isn't as aggressive and every now and then I need to connect to it to connect to a SOAP web service that operates on a blocked port.

Is there a ways (hotkey or system preference) that I can toggle so that I can remain connected to both networks, but force my MacBook to connect to the internet through the WiFi, rather than the local network?

Currently, I have to disconnect from the Thunderbolt display, and connect back up when I am finished downloading my data. Do I have any other options?

In the network control panel, click the gear at the bottom of the interface list and select "Set Service Order...". In that dialog, you can move your WiFi above the ethernet display.

Under Network on the system preferences, in on the wireless pane on the macbook pro, you should see Preferred Networks. Make sure the iMacs network is on top and all the require administrator authorization to: are unchecked.

Days later, I've finally figured it out. The com.apple.mDNSResponder.plist file located in /System/Library/LaunchDaemons/ was corrupted, and for some reason attempts to reset it were not being saved.

I copied this file from a macbook that was able to connect, and, since I'm using Lion, added in the option to allow appending search domains by inserting the line

<string>-AlwaysAppendSearchDomains</string>

in the following position:

<string>/usr/sbin/mDNSResponder</string>
<string>-AlwaysAppendSearchDomains</string>
<string>-launchd</string>

I then restarted the machine. This appeared to do the trick.
