Example config
You can find an example configuration in the docker-compose.yml included. In order for this to work, the container needs its own IP address. Create a network called public
like this:
docker network create -d macvlan \
--subnet=192.168.1.0/24 \
--gateway=192.168.1.1 \
--ip-range=192.168.1.2/32 \
-o parent=eth0 public
Now you can assign an IP to your container:
version: '2'
services:
app:
image: janwer/vpnc-relay
restart: always
env_file:
- vpnc-credentials.env
cap_add:
- NET_ADMIN
