vbox 5 host firewall blocks bridged networking, used to work in 4.3.20

[Frank Bevers]

I migrated from vbox 4.3.20 on a w7/64 host to vbox 5 & later to 5.01

I run Bitdefender Internet security on my host

VM's (w7) that used to work with bridged networking under vbox 4.3.20 no longer can access internet. Disabling the Bitdefender host firewall solves the issue. accessing local web resources on the intranet such as a NAS management webpage does work. So it looks like the new network adapter of 5.x is causing the issue

NAT does work with the host firewall enabled.

I forgot to add that the Bitdefender logs do not show any event.

Xref #14261, which sounds similar in its manifest effects.

I have uninstalled bitdefender internet security 2015 & replaced with ESET Smart Security 8; the eset firewall seems to deal OK with vbox5 bridged networking. So it comes down to how the Bitdefender firewall looks at the vbox5 network adapter I guess.

I tried to reinstall all, it didn't work (with revo)

I then shutdown my bitdefender firewall and set back to bridge with "promiscuity" authorized all to have the network working properly.
