I'm running into an issue where I have Vmplayer and VirtualBox VMs both bridged, using dhcp, reaches the external network, and other hosts on the network can ping all the VMs. However, Vmplayer VMs and VirtualBox VMs can't ping each other.
These are the test results:
Vmplayer VMs _can_ ping other Vmplayer VMs
VirtualBox VMs _can_ ping other VirtualBox VMs
Other hosts can ping _both_ Vmplayer VMs and VirtualBox VMs
Vmplayer VMs _can't_ ping VirtualBox VMs
VirtualBox VMs _can't_ ping Vmplayer VMs

gateways in your VB host's routes or are they relative to their adapter number?
