VirtualBox with Networking

[Chris Rothrock]

Alexander,

As a second part to thatm I took the DHCP part completely out of the
equation and set a static IP on both VMs and I was unable to ping between
the two VMs thereby taking the outside network completely out of the
picture.  In this case, the ping should have gone from one VM to the NIC
bridge then back to the second VM but that didn't occur either.  I will
also try Martin's suggestion with the NIC dump but there is certainly
something not routing properly with the bridge.
