Reported by: Rick Owned by:
Priority: critical Component: network/hostif
Version: VirtualBox 4.2.0 Keywords:
Cc: Guest type: Linux
Host type: Mac OS X

Description (last modified by frank) (diff)

An environment with a VM that has 2 types of networks: 1 NAT, 1 Host-Only
NAT works fine for world access but for internal access to the host, the IPv4 is not working even though IPv6 works fine

The host is running MacOSX 10.7.5
The Guest is an Ubuntu 11.10
