How to trick a router into recognizing an Airport Express as a computer

[is3al]

So my university internet (ResNet) does not permit wireless routers. I need to use more than one computer so I was looking to set my my Airport Express.

But registering the Airport Express directly as-it-is does no successfully go through. Is there a way I can trick the ResNet router to recognize the Express as a computer?

Will morphing the MAC Address of my MacBook Pro to the Express' MAC Address?

The ResNet uses a "Network Card Address" to recognize, I think. Is it the same as MAC Address.

Any insights would be appreciated! Thanks!

Set your Express to Share a Public IP address in the Internet Connection tab of the Internet pane. Configure IPv4 should be "Using DHCP". And give ResNet the Express' wired MAC address as your own for the "Network Card Address". That one of the fun things about having an Apple Airport device, networks can't easily tell if its a computer or Airport. Because Apple shows up as the device maker for both.
