Consider the following network plan \n\n```\n+-------------------------------------------------------------------------------------------------------------------+\n| |\n| |\n| 192.168.122.0/24 |\n| +------+ +--------+ |\n| 192.168.122.3/24 | | +-------------------------------+ | | 192.168.122.254/24 |\n| 10.0.0.1/24 | left +--+ ENCRYPTED IP-IN-UDP +-+ right | 10.0.1.1/24 |\n| | | +-------------------------------+ | | |\n| +------+ +--------+ |\n| | | |\n| +----------------------+ +------------------------+ |\n| | left internal net | 10.0.0.0/24 | right internal net | 10.0.1.0/24 |\n| +----------------------+ +------------------------+ |\n| | | |\n| +---------------+ +------------------+ |\n| | | | | |\n| | left node X | 10.0.0.10/24 | right node X | 10.0.1.10/24 |\n| | | | | |\n| | | | | |\n| +---------------+ +------------------+ |\n| |\n+-------------------------------------------------------------------------------------------------------------------+\n```\n\nWe can start this application on the left node like this:\n`./vpr -local 10.0.0.1/24 -key 1234123412341234 -remote 192.168.122.3 -route 10.0.1.0/24 -loglevel debug`\n\n\nSimilarly on the right node:\n`./vpr -local 10.0.1.1/24 -key 1234123412341234 -remote 192.168.122.254 -route 10.0.0.0/24 -loglevel debug`\n\n\nAnd then we can start pinging *from* a right node:\n`$ ping 10.0.0.10`\n\nOr a left node:\n`$ ping 10.0.1.10`\n\n## Docker\nYou can build\u0026run a container with the following commands:\n```\nsudo docker build -t test/vpr .\nsudo docker run -it -e REMOTE=87.14.33.12 --cap-add=NET_ADMIN --device=/dev/net/tun test/vpr\n```","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmoolen%2Fvpr","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmoolen%2Fvpr","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmoolen%2Fvpr/lists"}
