I have my iMac connected to the Campus Network. It needs to go through proxy port (8080 if it matters). This is all working perfectly. Now, how do I sort out my MBP's wireless so I can use Internet Sharing here? I had it working at home (no proxies) fine and here I can connect to my iMac but not the internet through my iMac. There must be a way of doing this? They have a network set up between them that is working. How do I fix this? I get the feeling it's probably quite easy.
