Some troubleshooting should be helpful. ifconfig, resolv.conf. Then try to go out. Ping, traceroute. The very problem might be on mac. It has to pass and probably nat packets. If I remember well, the kernel is mach, microkernel. It is different than freebsd and resembles hurd in some instance. You should have forwarding allowed, not just in firewall, I think. Then, new macs use modern protocols like "n". Check again all options to have "g" included. At first, try name resolution. Zoran
