Here is a quick guide to help you configure LXC external IP in a few easy steps. Our LXC/LXD Support team is here to lend a hand with your queries and issues.

How to configure LXC external IP

Configuring an external IP for an LXC container involves assigning a unique static IP address to an LXC container.

This makes the container accessible from other devices on the network, and the Internet, in case the host system has a public IP address.

According to our experts, this process involves setting up a network bridge between the LXC container and the host system. This offers network access to the container network as if it were a separate physical device.

Besides assigning the static IP address to the container, we also have to configure additional network settings, like the default gateway, network mask, and DNS servers.

Our experts would like to point out that the LXC external IP has to be unique. Furthermore, we can ensure the IP address is not duplicated by using the Address Resolution Protocol (ARP) scan to verify the IP address is unique.

Let’s take a look at how we can configure an LXC external IP:

1. To begin with, we have to start the LXC container:

   phpCopy codelxc start
2. Then, verify the contianer’s network configuration as seen here:

   phpCopy codelxc network show
3. Next, we can configure the network bridge so that it assigns a static IP address to the container:

   phpCopy codelxc network set ipv4.address /
4. Now, it is time to restart the container.
5. After that, we can verify the IP address has been assigned by taking a look at the network configuration of the container:

   phpCopy codelxc network show
