<\/a><\/p>\nNetwork Types<\/h3>\n
VirtualBox supports di\ufb00erent types of network con\ufb01guration similar to physical network con\ufb01guration.<\/p>\n
- \n
- NAT(Network Adress Translation)<\/li>\n<\/ul>\n
NAT is a default option when VirtualBox is installed. VirtualBox provides a NAT router and DHCP
\nservice for every virtual machine.
\nThe same IP address 10.0.2.15 is assigned to all virtual machines from the DHCP in the VirtualBox
\nand the default gateway address is 10.0.2.2.
\nAll virtual machines can access to the pyhsical network through the NAT provided by the virtualBox.
\nBut access to VM from the outside is not allowed.<\/p>\n![\"\"](\"https:\/\/gotocloud.co.kr\/wp-content\/uploads\/2024\/01\/NAT-300x204.jpg\")
<\/a><\/p>\n- \n
- NAT Networking<\/li>\n<\/ul>\n
All virtual machines are connected to the virtual switch and can access to the physical network
\nthrough the NAT like a wi\ufb01 router at home.
\nDi\ufb00erent from NAT, each virtual machine has di\ufb00erent IP address but shares the same gateway in the
\nVirtualBox. Each virtual machines can connect to each other.<\/p>\n![\"\"](\"https:\/\/gotocloud.co.kr\/wp-content\/uploads\/2024\/01\/NAT_Netwok-300x204.jpg\")
<\/a><\/p>\n<\/p>\n
- \n
- Bridged Networking<\/li>\n<\/ul>\n
All virtual machines and host machine are bridged in the same ethernet segment. In other words, all<\/p>\n
virtual machines are connected to the physical network directly.<\/p>\n
In this networking, all virtual machines are accessible from the outside network.<\/p>\n

<\/a><\/p>\n- \n
- Internal Networking<\/li>\n<\/ul>\n
All virtual machines are connected to the virtual switch and can access each other but isolated from<\/p>\n
the host machine and outside network.<\/p>\n
All virtual machines can not access to the pyshical network and also the host machine can not access<\/p>\n
to all virtual machines.<\/p>\n

<\/a><\/p>\n- \n
- Host-only Networking<\/li>\n<\/ul>\n
All virtual machinesand host machine are connected to the virtual switch and can access each other<\/p>\n
but isolated from the outside network.<\/p>\n
The only di\ufb00erence is that the host machine is added into the internal network.<\/p>\n
