I have an ubuntu pc (ip: 22.214.171.124) set up which should be connecting through a switch to my iMac(ip: 126.96.36.199) in order to gain internet access. The iMac has "share internet connection" turned on. I've added the iMac ip in the gateway, DNS and search domain field in the configuration for the eth0 on the ubuntu pc. I also added the iMacs's ip as proxy for all services. I can ping each other pc/Mac, but the only thing my ubuntu pc gets, when calling any URL is my addressbook server web admin page.
Any idea what I've done wrong or how to set this up the right way.
