I tried both of these systems: - Host: Vista Home Premium 6.0 Build 6001 Service Pack 1 - Guest: Checkpoint !SecurePlatform - Host interface: Intel Pro/Wireless 3945ABG. - Guest interface: PCnet-FAST III (Am79C973) - Host: Vista Ultimate 6.0 Build 6000 - Guest: Fedora 10 - Host interface: Intel Pro/Wireless 3945ABG - Guest interface: PCnet-PCI II (Am79C970A) or Intel PRO/1000 MT Desktop (82540EM) The problem is strictly DNS. Because when I try to reach web sites over HTTP using their IP addresses I can do that. It seems every other traffic type is working but DNS. Check the output of the following commands please: {{{ [Expert@cpmodule]# cat /etc/resolv.conf nameserver 195.175.39.40 nameserver 195.175.39.39 [Expert@cpmodule]# ping 195.175.39.40 PING 195.175.39.40 (195.175.39.40) 56(84) bytes of data. 64 bytes from 195.175.39.40: icmp_seq=0 ttl=247 time=39.2 ms 64 bytes from 195.175.39.40: icmp_seq=1 ttl=247 time=32.4 ms --- 195.175.39.40 ping statistics --- 2 packets transmitted, 2 received, 0% packet loss, time 999ms rtt min/avg/max/mdev = 32.410/35.849/39.288/3.439 ms, pipe 2 [Expert@cpmodule]# ping 195.175.39.39 PING 195.175.39.39 (195.175.39.39) 56(84) bytes of data. 64 bytes from 195.175.39.39: icmp_seq=0 ttl=252 time=29.5 ms 64 bytes from 195.175.39.39: icmp_seq=1 ttl=252 time=28.6 ms --- 195.175.39.39 ping statistics --- 2 packets transmitted, 2 received, 0% packet loss, time 1003ms rtt min/avg/max/mdev = 28.633/29.101/29.570/0.498 ms, pipe 2 [Expert@cpmodule]# nslookup google.com ;; connection timed out; no servers could be reached [Expert@cpmodule]# nslookup google.com 4.2.2.4 ;; connection timed out; no servers could be reached [Expert@cpmodule]# ping 74.125.67.100 PING 74.125.67.100 (74.125.67.100) 56(84) bytes of data. 64 bytes from 74.125.67.100: icmp_seq=0 ttl=242 time=167 ms 64 bytes from 74.125.67.100: icmp_seq=1 ttl=242 time=174 ms --- 74.125.67.100 ping statistics --- 2 packets transmitted, 2 received, 0% packet loss, time 1000ms rtt min/avg/max/mdev = 167.857/171.396/174.936/3.563 ms, pipe 2 }}} " defect closed network VirtualBox 2.2.0 invalid dns,bridged networking Linux Windows
