Wireless Inteface Configure As Bridge
Hi,
I m using CentOS 7 in laptop and kvm as virtualization to run windows guest vm.Currently i m using NAT as default setting for guest vm, my internet is fine but can’t resolve some domains and sites.
So want to come on bridge.
As per my understanding bridge can not work while device is managed by NetworkManager.
Is there any utility or tool to use to scan wireless device in network and connect them as i want to stop to use Networkmanager to use laptop wireless interface as bridge for my guest vm.
Thx Ben

You cannot do what you want

“Note that a bridge cannot be established over Wi-Fi networks operating in Ad-Hoc or Infrastructure modes. This is due to the IEEE 802.11
standard that specifies the use of 3-address frames in Wi-Fi for the efficient use of airtime.”

Alexander is correct. It is not possible to bridge a wireless network to a wired network and have it function properly.
You can NAT MASQUERADE though. (And that’s probably your [only?] other alternative.)
According to the Red Hat RHEL7 Networking Guide you can’t bridge wireless interfaces. IIRC there’s a reason mentioned in that guide and here’s another one (answer 1):

However there’s a debian wiki entry that says it’s possible using ebtables:

I’m writing this post in my OS/2 guest, running bridged to hosts WiFi adapter in Virtual Box.. Host is right now Fedora 20, but can be Win7 also. Maybe Virtual Box has some tricks to do this – I don’t know; but if for sure works fine on this laptop.
