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=30
BRIDGE_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
