alpine-l2tp-vpn-client

An Alpine based docker image to setup an L2TP over IPsec VPN client w/ PSK (and optionally Socks5) within the container.

Run

Setup environment variables for your credentials and config:

export VPN_SERVER='YOUR VPN SERVER IP OR FQDN'
export VPN_PSK='my pre shared key'
export VPN_USERNAME='[email protected]'
export VPN_PASSWORD='mypass'
export SCOKS5_ENABLE=0

Now run it (you can daemonize of course after debugging):

docker run --rm -it --privileged \
           -e VPN_SERVER \
           -e VPN_PSK \
           -e VPN_USERNAME \
           -e VPN_PASSWORD \
              wuamin/alpine-l2tp-vpn-client

You can use .env file:

source .env;docker run --rm -it --privileged --env-file .env -p ${SCOKS5_PORT}:1080 wuamin/alpine-l2tp-vpn-client

Socks5

If you set SCOKS5_ENABLE to 1 (default value is 0), the container will run dante at startup to provide a socks5 proxy (via VPN). Don not forget to expose port 1080.

export SCOKS5_ENABLE=0
export SCOKS5_PORT=1080
docker run --rm -it --privileged \
           -e VPN_SERVER \
           -e VPN_PSK \
           -e VPN_USERNAME \
           -e VPN_PASSWORD \
           -e SCOKS5_ENABLE \
           -p ${SCOKS5_PORT}:1080 \
              wuamin/alpine-l2tp-vpn-client

Debugging

On your VPN client localhost machine you may need to sudo modprobe af_key if you're getting this error when starting:

pluto[17]: No XFRM/NETKEY kernel interface detected
pluto[17]: seccomp security for crypto helper not supported
