Yes, I was hopeful that things would work following the simple instructions in the article. I am using an iBook connected to the internet via airport and tried to use a firewire cable to connect my G4 tower to the internet via my iBook. (0S 10.3.8 on both machines).
I have turned off firewalls on both machines, turned on personal file sharing, and turned off the firewall on my wireless adsl modem/router as well.
The G4 seems to connect via the firewire as it is assigned an IP address and locates the router, but I can't connect when I open Safari. Also, when I check the connection using Network Utilities, there is a 100% packet loss with the PING function.
I'm a relatively experienced mac user but I still for the life of me am unable to figure this one out. I would be eternally grateful to anyone who has any ideas on how I can fix this problem!
