Ticket #10593 (new defect)
arp mac address collision if DHCP server has same IP as host-only adapter
|Reported by:||VirtualBox User||Owned by:|
My guest's network adapter is set to host-only mode. In File..Preferences..Network, if I modify my host-only adapter so that the IPv4 address matches the DHCP server address, arp requests from the guest will get two replies from two mac addresses: one from the host OS and one from the DHCP server.
Sometimes the guest OS will pick the mac address corresponding to the host. When this happens, networking works fine. When the guest OS picks the mac address corresponding to the DHCP server, networking stops working because packets destined to the host are sent to the wrong mac address.
