| 7 | <p>In NAT mode, the guest network interface is assigned to the IPv4 range
|
|---|
| 8 | <codeph>10.0.<varname>x</varname>.0/24</codeph> by default where <varname>x</varname> corresponds to the
|
|---|
| 9 | instance of the NAT interface +2. So <varname>x</varname> is 2 when there is only one NAT instance active. In that
|
|---|
| 10 | case the guest is assigned to the address <codeph>10.0.2.15</codeph>, the gateway is set to
|
|---|
| 11 | <codeph>10.0.2.2</codeph> and the name server can be found at <codeph>10.0.2.3</codeph>. </p>
|
|---|
| 12 | <p>If the NAT network needs to be changed, use the following command: </p>
|
|---|
| 13 | <pre xml:space="preserve">$ VBoxManage modifyvm <varname>VM-name</varname> \
|
|---|
| 14 | --natnet1 "192.168/16"</pre>
|
|---|
| 15 | <p>This command would reserve the network addresses from <codeph>192.168.0.0</codeph> to
|
|---|
| 16 | <codeph>192.168.254.254</codeph> for the first NAT network instance of <varname>VM-name</varname> The guest IP
|
|---|
| 17 | would be assigned to <codeph>192.168.0.15</codeph> and the default gateway could be found at
|
|---|
| 18 | <codeph>192.168.0.2</codeph>. </p>
