Using Host-Interfacing and Bridging on VirtualBox

NAT interface on guest OS gives limitation so we may need to add a new virtual interface to it. This is called ‘HIF’ (Host Interface).

Steps:

1. Install bridge-utils, if not yet installed:

   sudo yast -i bridge-utils

2. edit /etc/sysconfig/network/ifcfg-br0 and write:

BOOTPROTO='dhcp'NETMASK='255.255.255.0'STARTMODE='auto'USERCONTROL='no'DHCLIENT_TIMEOUT=30BRIDGE_PORTS='eth0'

3. Edit /etc/sysconfig/network/ifcfg-eth0 and change the content to:

   BOOTPROTO='static'IPADDR='0.0.0.0'

4. Create a new permanent interface:

   VBoxAddIF tap0  br0

5. Configure the guest to have the second Virtual Network Interace and assign ‘tap0′ as its name
