virtualbox.org

I just upgraded to 4.3.2 from one of the 4.2 releases and I can no longer access the internet on my Windows XP guest. According to XP, it has an IP address and says it's sending and receiving, but I can't get on the internet with Firefox, or download automatic software updates, or even ping Google. I'm using a Bridged Adapter with the Intel PRO/1000 T Server adapter type. I've tried promiscuous mode in Deny and Allow All (and frankly, I'm not really sure what that setting does). I'm running Snow Leopard, and I do have Net Barrier running, if that helps. I don't see anything Virtualbox related running in the Net Barrier window though. Please help. Thanks.

Can you ping another computer on your network and/or your router?

I can access the router web interface via 192.168.1.1. I haven't specifically tried pinging something else on the network.

If you can ping your router, then Virtualbox is working perfectly fine - providing hardware network link. Your network configuration is most likely wrong somewhere - being IP or network devices.
