Hi
I've been using VirtualBox successfully on OSX for a number of years. I'm currently on 5.0.0 RC2 (had to roll back from RC3 due to headless issues discussed elsewhere).
I've just uncovered the following - I think it's more an OSX issue than VB, but here goes.
Subsequent to update to 10.10.4, I noticed my win 7 vm was not getting an IPv4 address (DHCPv6 completes ok) when the vm is bridged to wireless - but NOT when bridged to ethernet. I tried firewall enable/ disable, but no result.
Packet capturing on the server reveals the my DHCP does send an offer - but the offer doesn't show up when capturing on the en0 (wifi interface).
But the macbook DOES get an address - I'm guessing because it's got the Bootp unicast flag set and thus the offer is unicast - whereas windows asks for a broadcast offer.
This suggests to me that Apple have made the wireless driver drop IP broadcasts. Can anyone think of a work around?
Thanks in advance,
osx 10.10.4 vm on wifi

Please do not report problems with beta versions of VirtualBox outside of the beta forum.
Moving this topic to the beta forum.

My apologies for mis-posting - and for re-posting - I thought it was going to simply get deleted.
Update - I've tried on RC3 10470 - same result - can't do DHCPv4 across a bridged interface.

I deleted your re-post.
Re: osx 10.10.4 vm on wifi
Very confused now - problem has disappeared!
Two things have changed:
1) I'm in someone else's house and therefore talking to another DHCP server (vanilla dsl home router)
2)(just a bit more tenuous) - I ran a disk/ permisssions repair and got slew of corrections.
At any rate, until I get home and try again with my ISC DHCP server next week I have no way of reproducing the issue.
But I think it's almost certainly not a VB issue we're looking at ( guessing you may have reached this conclusion already
)
Thanks for a great product.

I've finally figured this issue out and it's not the OSX host system and it's definitely not VB!
It's the embedded AP in my Cisco 887 router and I found the solution here:
https://supportforums.cisco.com/discuss ... omous-mode
Simply go into the AP's cli, get into config:
int bvi 1
ip helper-address x.x.x.x (address of your DHCP server)
Anyone who knows the significance of these commands will protest that these should only be required if the AP is routing, not switching. I know it's counter-intuitive but I have demonstrated it works.
Hope someone finds this useful.
