Deactivation of NIC at host

Post by caspertone »

I need just a guest doing NAT so that internet can be browsed from the guest. Does this need the "VirtualBox Host-Only Network" NIC activated or may I deactivate it?
Thanks.

NAT does not require the host-only adapter. As implied by the name, the host-only adapter is only used by host-only networking mode.

Thank you for confirming my impression. I could not find any explicit reference in the manual -just the nic name ...
Now I am tempted to use the *NdisDeviceType trick ...

I wonder why VB installation installs this NIC and set ups it active even in many users will not be using it; perhaps this could be done when a user selects to use host-only networking with a guest ...

Thanks again.

When you install VirtualBox you are given a list of optional components and you can decide which ones you want.

If you do not want the Host Only (or any other) option, do not install it.

Thanks for that, I am not conscious of having seen that options ... will take care next time!
