I live in a building where I am connected to the university network for internet. I am not allowed to connect a router, or I will be kicked off the network. (This rule was created after wrongly configured routers blocked internet access for the entire building.) They expect people to connect their computers all through ethernet.
I have multiple computers including a MBA and an iPad, so I don't plan to abide by this.
I know I could configure one of my Macs for internet sharing, but it would have to be running all the time. Since I own an Airport Express I was hoping I could use it instead. Is there a way to configure the Airport so that the network administrators can't detect I'm using a router?
