I got a weird 'problem'. I recently started to protect my wireless-router. I order to do this I had to enter the mac-adresses into the Firewall-part of my SMC modem/router. After I did this, it is no longer possible to go to the internet through the cable connection. What is working: Wireless (so I don't have a real problem ) My Powerbook does see my Powermac. (The shares are working, but ping doesn't work) Does anybody have a clue? Just curious. Thanks.
