I've installed Debian in my VirtualBox (my host OS is Ubuntu). And there I configured two network interfaces: eth0 as NAT, and eth1 as Bridge.

NAT I need to have access to the internet in virtual OS, but Bridge I need because I want this virtual OS to be a part of my local network.

How to switch from these network interfaces? For example now I use eth0 (NAT), but some time later I need to turn off eth0 and turn on eth1.

P.S. There is no Desktop Environment in guest OS (Debian), so I need to do this in terminal.

Thanks in advance.

If both interface are configured in /etc/network/interfaces you can use

sudo ifup eth0

to bring eth0 up and

sudo ifdown eth0
