Hi. So, for the past year, I've been receiving WiFi internet on my iMac, and sharing it via ethernet and sometimes FW800. Lately, mostly just ethernet. As of 10.8.2, this has stopped functioning. I have heard many rumors about internet sharing issues in the update, but it seems I am in the extreme minority in terms of sharing internet via ethernet rather than sharing it via WiFi.
For the record, what I have tried so far is, enabling and disabling all options, trashing preferences, creating a second administrator account on the iMac and trying from that one, switching multiple ethernet cables just in case, and even switching to a different wireless network (we have two in my home on different wavelengths). It's always the same: devices recognize that they're connected to the ethernet port on the iMac. The iMac recognizes it's connected to them. They can obtain their own IP addresses through DHCP, but they cannot, under any circumstances, actually connect to the internet.
Please help! I'm tearing my hair out over here, as this was crucial to my setup. Updates shouldn't work this way.
