WireGuard Setup

Host Requirements

Load the WireGuard kernel module on the host:

kldload if_wg
echo 'if_wg_load="YES"' >> /boot/loader.conf

VNET Required

This container requires its own network stack. Add the annotation:

1	`--annotation 'org.freebsd.jail.vnet=new'`

Getting VPN Credentials

From your VPN provider (Mullvad, PIA, ProtonVPN, etc.), get: - Private Key - Your client private key - Public Key - The VPN server's public key - Endpoint - Server address like vpn.example.com:51820 - Address - Your assigned tunnel IP

Kill Switch

Traffic is routed through the VPN interface. If the VPN connection drops, Transmission loses connectivity - no IP leaks.

Verifying VPN

Check your public IP from inside the container:

podman exec transmission-wireguard fetch -qo - https://ifconfig.me

Implementation Details

Architectures: amd64
User: bsd (UID/GID set via PUID/PGID). Defaults to 1000:1000.
Base: Built on ghcr.io/daemonless/base (FreeBSD 15.1).
