When deploying a Vultr cloud server with a private network, you need to manually configure the private adapter. The examples shown in this guide are IPv4, but Vultr supports both IPv4 and IPv6. Vultr also supports multiple VLANs over a single private network interface with 802.1q tags. You'll find your server's information on the information page under Settings > IPv4. In the example below, the public network address is 192.0.2.123, and the private network address is 10.10.10.3. You'll find configuration samples for your server by clicking "View our networking configuration tips and examples."
Verify that private networking is enabled for your cloud server. Your private network device is vio1. Your public network device is vio0.
Change 10.10.10.3 to the selected private IP address and replace the contents of /etc/hostname.vio1
with:
inet 10.10.10.3 255.255.240.0
!ifconfig vio1 mtu 1450
Restart the interface or reboot.
# sh /etc/netstart vio1
# reboot
The Vultr API offers several endpoints to manage private networks.
