WireGuard inside LXC on Proxmox

We can definitely set up WireGuard VPN inside an LXC container in Proxmox. This enables us to build a secure network tunnel so that the devices may communicate. Here is a general overview of the methods to obtain this:

1. Make sure to allocate the appropriate resources, such as CPU, memory, storage, and network interfaces, when creating a new LXC container on Proxmox.

2. Make sure that nested virtualization is enabled for the LXC container if we intend to use WireGuard with nested virtualization (running WireGuard inside a container inside a virtualized environment).

3. SSH or the Proxmox web portal can be used to access the container.

4. Using the package manager of the operating system of the container, update the package repositories and install WireGuard. As an illustration, in Debian/Ubuntu:

sudo apt update 

sudo apt install wireguard

5. Use the wg command-line tools inside the container to generate WireGuard keys.

6. Inside the container, create the wg0.conf WireGuard setup file. In this file, configure the network settings, private and public keys, permitted IP addresses, and peers.

7. Allow the traffic on the WireGuard port by setting up the container’s network options (the default configuration is UDP 51820).

8. Set up the Proxmox host such that communication from the host’s public IP forwards to the container’s WireGuard port. It needs to set up NAT rules or port forwarding.

9. Install WireGuard on the client devices, such as laptops or other servers, by setting up it with the LXC container, the client’s private and public keys, and the client’s private and public keys.

10. Check the LXC and the client devices’ connectivity to make sure the WireGuard tunnel is operating as it should.

11. Make sure that both the Proxmox host and the LXC firewall options allow incoming and outgoing WireGuard traffic.

Conclusion

The particular setup, the Linux distribution we’re using inside the container, and any additional network concerns may affect how this procedure goes. Our Tech team can assist you with precise and comprehensive instructions.
