I have the networking setup described here:
Currently, I can ping my DNS server but all DNS requests fail:
~$ ping 188.8.131.52 PING 184.108.40.206 (220.127.116.11) 56(84) bytes of data. 64 bytes from 18.104.22.168: icmp_seq=1 ttl=57 time=105 ms 64 bytes from 22.214.171.124: icmp_seq=2 ttl=57 time=111 ms ^C --- 126.96.36.199 ping statistics --- 2 packets transmitted, 2 received, 0% packet loss, time 1000ms rtt min/avg/max/mdev = 105.604/108.388/111.172/2.784 ms ~$ nslookup oracle.com 188.8.131.52 ;; connection timed out; no servers could be reached
I can think of no good reason for this, because Ubuntu is (to my knowledge) not running a firewall. However, Ubuntu is virtualized, so I hope that it isn't something wrong with the way that its VirtualBox host is set up.
