WireGuard Setup Assistance

[Najdat]

Hi,

I’m having issues getting WireGuard working on Proxmox VE and was hoping for some guidance. I installed WireGuard using the script provided in Proxmox VE Helper-Scripts, running inside an unprivileged LXC container.

Environment details:

Proxmox VE

WireGuard installed via Proxmox VE Helper-Scripts

LXC container (unprivileged)

Vodafone Station router

IPv4 enabled (no CGNAT)

UDP port 51820 forwarded to the container

Dynamic DNS configured via afraid.org

WireGuard starts correctly, but the tunnel does not establish (no handshake). Current status inside the container:

interface: wg0
listening port: 51820
peer:
allowed ips: 10.0.0.2/32

The interface is up and listening, but clients cannot connect.

Please let me know what additional information is needed (LXC config, Proxmox firewall status, WireGuard configs, sysctl settings, etc.), and I’ll provide it.

Thanks.
