Bridged networking problem with 4.1.2

[rbauer11]

Running ClearOS as a virtual gateway, nic 1 controlled by guest and connects to internet, nic 2 is bridged for local network and host connections. I currently have no computers connected to nic 2 except the host. Under vbox 4.0.12 host could connect to internet without issues. Under vbox 4.1.2 host connection is only available if another computer is connected to nic 2 as well.

Only workaround I've found so far is to revert back to version 4.0.12.

host: OpenSUSE 11.4, kernel version 2.6.37.6-0.7-Desktop guest: ClearOS 5.2 sp 1 (based on Centos Linux distro)
