At the moment, i'm sharing my cable connection amongst my home network using the built-in 'Internet Sharing' in OS X. I understand this uses a DHCP server. Everthing works fine and all other machines on the network can get an IP of the form 192.168.2.x. My question is - how do I change this so the other machines get an address of the form 192.168.0.x? I don't mind getting my hands dirty in UNIX config files. Any ideas?
