Starting with the latest update of Mac OS X (10.6.5) all Apple applications (Safari, Mail, iChat, etc.) don't connect to the internet anymore, if the assigned IP address is from the 169.254.0.0./16 range. This is not a routing problem, I can still ping any server I want, even connecting via command line tools works.
I know this problem could easily be fixed by changing the IP address to a more common RFC1918 address (e.g. 192.168.0.0./16), but this is what the ISP assigns via DHCP and I am not sure I can convince them (Xplornet) to change that.
So I am wondering if there's a (hidden?) setting that would convince Apple applications, that they are in fact still online.
I know the ISP is doing it wrong, really wrong. I've thought of a router, too. Unfortunately the Apple computer I'm talking about is on the other side of the big pond and I am not sure if my in-laws will be able to configure that thing correctly without me assisting via screen sharing (which would not work while doing it...). That's why i'd love to have a pure software solution. – WMR – 2010-12-17T12:27:33.843
well most routers nowadays will have automatic dhcp on lan side, and dhcp client on wan side. the only thing you need to do would be to instruct your in-laws to shutdown the wifi or secure it... and you can consider TP-link routers as they are fairly stable, and they have emulator online..

Adding a router worked well. – WMR – 2011-09-06T20:53:35.577
