VirtualBox Host Networking Multiple Taps
After the creation of the first tap you can create additional taps and connect them to the single bridge off the ethernet connection. For example the following is my setup for an additional tap. sudo tunctl -t tap1 -u username sudo /usr/sbin/brctl addif br0 tap1 sudo ifconfig tap1 192.168.0.12 up sudo bash -c ‘echo 1 > /proc/sys/net/ipv4/conf/tap1/proxy_arp’ sudo route add -host 192.168.0.5 dev tap1 sudo arp -Ds 192.168.0.5 eth0 pub You want all IP addresses to be unique otherwise there will be conflicts. Do consider the IP address you want to provide to the Guest OS. Note that you can specify the MAC address of the VirtualBox ethernet card in the VirtualBox configuration menu. This is useful if you want to configure a static IP address to be supplied to your Virtual OS. This post is superseded by a more recent post.
