OS X Connection problems, AOEII in Parallels

I just downloaded the latest version of Windows XP, the 64-bit one. And installed it in Parallels on my late 2012 iMac. Age of Empires II runs like a charm.

However, when I try to connect to somebody running the same version of AOE it won't show that user's game. I know the fault is with me because others have been able to connect.

I disabled the firewall in Windows XP and the iMac is connected directly to the Internet so there are no hardware intermediaries that can mess things up.

But of course the big elephant here is OS X and Parallels, could it mess something up? Anyone has any ideas what I could do to solve this?

I posted a little too quick. But now that I posted it, I'd like to leave the solution for others who may search for it.

The solution is the same which is described here: http://hintsforums.macworld.com/archive/index.php/t-82668.html

I use Parallels 8 and that topic is about Parallels 3, but it works just the same. You need to right click on the Parallels Desktop icon in the dock with your virtual machine running, go to devices and then network. Choose "Ethernet" instead of the default Internet adapter.

I restarted my machine after doing that but it could very well work without a restart. After the restart, Age of Empires II worked immediately.
