How to configure mac book pro to act as an Access Point (and not a router)? I am connected to internet via ethernet cable on my MBP laptop. I want to have access to internet wirelessly on my iPad as well. How can I config my MBP (OSX 10.6.8) to act as an "Access Point" ?

I already tried the internet sharing via system preferences. 
I could connect to my shared network on my iPad, but the problem is my ISP does now allow network sharing! On my iPad it shows the following error message:

"We have detected that you are using a router or a device that is performing network connection sharing. Sharing a connection with multiple devices is against out term of use."..."You can use a router on our network, however it must be configures to act as an access point."
Then it mentions that I should turn off DHCP in the router settings.

I am in a student residence and do not have access to the ISP's support staff.
The description of the my internet connection contract says that I have right to use two devices manually. There is one ethernet socket in the room.

How can I get internet in my iPad? 

Thanks
Just replace the word router with your Mac.


  If you are living in student accommodation and you would like to use a
  router (in your case the MBP), then you must follow the below
  instructions to ensure it is correctly configured for use on our
  network. Using a router that performs the DHCP service is against our
  terms of use. Failure to disable the DHCP service of your router may
  result in your connection being suspended.
  
  If you are living in residential accommodation, your router does not
  need to be re-configured. Please see our FAQs for more information.
  
  1) Connect the power cable to your router, and connect your router to
  your PC using an Ethernet cable. This cable needs to go from one of
  the LAN ports on the router into an Ethernet port on your PC. Please
  see the diagram below.
