Does tcpdump on the host show outgoing connections to an external IP address (not a domain name)? For example, try opening to http://172.99.69.163/ from inside the guest and check that there is a TCP SYN packet sent from the host to 172.99.69.163. Do the hostfwd ports still work while internet access is down? Stefan
