DDoS-Filtered IP Configuration - RamNode Cloud VPS Documentation

You will need to configure your DDoS-filtered IP manually after your order is processed. The IP, gateway, and netmask have been provided to you via email. Please use the configuration examples below as needed.

Netplan Configuration (Ubuntu/Debian)

Log into your server

Connect via SSH to your instance.

Get root access

sudo -i

Create configuration file

nano /etc/netplan/60-filtered-ip.yaml

Add configuration

Add the following, replacing it with your IP and interface information:

network:
  version: 2
  ethernets:
    <adapter name>:
      addresses:
        - <your filtered IP>/<netmask>
      gateway4: <filtered IP gateway>
      nameservers:
        addresses: [8.8.8.8, 8.8.4.4]

Note: Adapter typically starts with eth or ens. You can find it with ip addr show or ifconfig.

Apply changes

Apply your changes:

netplan apply

Or verify first with:

netplan try

Verify configuration

Confirm the IP was added properly:

ip addr show

Interfaces Configuration (Debian)

Disable cloud-init network

Create a new cloud-init configuration file:

/etc/cloud/cloud.cfg.d/95-debian-network-config.cfg

With contents:

network: {config: disabled}

Comment out cloud-init interface

Edit /etc/network/interfaces.d/50-cloud-init.cfg and comment all lines related to eth0 (or any interface you want to statically configure).

Configure static IP

Edit /etc/network/interfaces. Replace iface eth0 inet dhcp with:

iface eth0 inet static
    address <your IPv4 address>/24
    gateway <your IPv4 gateway>

Add IPv6 (optional)

You can add IPv6 the same way:

iface eth0 inet6 static
    address <your IPv6 address>/64
    gateway <your IPv6 gateway>

Apply changes

Save and close the file. Then run:

ifdown eth0;ifup eth0

Or simply reboot:

reboot

Success! Your DDoS-filtered IP should now be configured and active. You can verify connectivity by pinging the IP address or accessing services running on your server.
