Do these system get all their network information through DHCP? Anyway check with "/sbin/route -n" on a Linux machine and the equivalent on your MAC, the routing information they use. It should look like: Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo 0.0.0.0 192.168.1.254 0.0.0.0 UG 0 0 0 eth0 Here 192.168.1.254 is the IP address of the router, could be in your case 192.168.1.1. > Things are fine connecting between the guest and the host.
