At work, we have a real old (graphite) Apple Airport Base Station (cache), which needed to be configured as DSL router for some wireless clients.
Fine, no problem, fire up Airport Admin on the iBook, configure all the DSL logins and set the thing up for NAT (as I kept the previous ESSID and WEP settings, I had no problem connecting from the wireless side and setting the thing up).
I do all that, see from the Airport status symbol that DSL is connected, but I can't reach anything through the access point (except the base station itself on the internal network).
After much searching around (even dumping PPPoE traffic on the DSL side with ethereal), I still can't find the problem. Connecting with another client works fine, no problems getting to Internet destinations.
Finally, I notice that my iBook's MAC address is not in the access list on the Base Station, and the thing somehow invalidates packets passing through to the PPPoE side. Still, I could connect to and configure the Base Station itself without problems.
Great security, no wonder wardriving was so much fun for quite a time.
