I have set up a version of Ubuntu 12.04 under VirtualBox (version 4.1.18) using NAT and everything works fine (using DHCP of course). I am running OS X Lion 10.7.4.
However, as soon as I switch the network to a Bridged Network, the Ubuntu VM experiences very odd networking problems. The machine appears to get a DHCP address assigned just fine, but after it can only ping itself and the IP of the VM's host machine. It cannot ping the gateway or the outside world.
I have checked lots of things:
- I have changed the network adaptor type but that makes no difference.
- I have tried rebuilding Linux from scratch, but at the start it is unable to connect to the Internet
I've checked the network settings, and the settings are correct. Here is a copy of ifconfig:
eth0 Link encap:Ethernet HWaddr 08:00:27:e4:1c:13 inet addr:192.168.1.13 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::a00:27ff:fee4:1c13/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:374 errors:0 dropped:0 overruns:0 frame:0 TX packets:77 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:33089 (33.0 KB) TX bytes:9509 (9.5 KB)
and route -n:
Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 192.168.1.1 0.0.0.0 UG 100 0 0 eth0 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
Please note that I am bridging my wireless port as that is the only port connected to the Internet. I know there are supposed IPv6 limitations, but I am not using IPv6.
Thanks for any help, this has been quite frustrating to solve.
