Having just upgraded to 10.5.4, my shared networking has failed. I still have access to all computers on the virtual network (10.211.55.x), but I don't have access from them to the internet. It appears to be parallels NAT failing, as everything else has remained as it should be (the firewall doesn't seem to pick up any of my 'ping's to the internet - they get caught by an allow rule. I've disabled the builtin firewall btw, and am using ipfw, as it allows much more understandable firewalling) Anyone else noticed this?
