Have you tried enabling 'Internet Sharing' as well as 'File Sharing' (same pref dialogue box)?

Thanks for your reply. Of course I had. Otherwise, I would have never been able to share internet to my MBP, iPhone, PS3 and my friend's BB or, the other way, see the iMac in the network. If I check the two boxes, internet prevails and sharing does nothing. Once again: until a week ago, I always could do both things simultaneously, but it's a recent problem which hadn't before.
