| 8 | In NAT mode, the guest network interface is assigned to the IPv4
|
|---|
| 9 | range <codeph>10.0.<varname>x</varname>.0/24</codeph>
|
|---|
| 10 | by default where <varname>x</varname> corresponds to the
|
|---|
| 11 | instance of the NAT interface +2. So
|
|---|
| 12 | <varname>x</varname> is 2 when there is only one NAT
|
|---|
| 13 | instance active. In that case the guest is assigned to the
|
|---|
| 14 | address <codeph>10.0.2.15</codeph>, the gateway is set to
|
|---|
| 15 | <codeph>10.0.2.2</codeph> and the name server can be found at
|
|---|
| 16 | <codeph>10.0.2.3</codeph>.
|
|---|
| 17 | </p>
|
|---|
| 18 | <p>
|
|---|
| 19 | If the NAT network needs to be changed, use the following
|
|---|
| 20 | command:
|
|---|
| 21 | </p>
|
|---|
| 22 | <pre xml:space="preserve">$ VBoxManage modifyvm <varname>VM-name</varname> \
|
|---|
| 23 | --natnet1 "192.168/16"</pre>
|
|---|
| 24 | <p>
|
|---|
| 25 | This command would reserve the network addresses from
|
|---|
| 26 | <codeph>192.168.0.0</codeph> to
|
|---|
| 27 | <codeph>192.168.254.254</codeph> for the first NAT network
|
|---|
| 28 | instance of <varname>VM-name</varname> The guest IP
|
|---|
| 29 | would be assigned to <codeph>192.168.0.15</codeph> and the
|
|---|
| 30 | default gateway could be found at
|
|---|
| 31 | <codeph>192.168.0.2</codeph>.
