Decentralized VPN
The RadVPN doesn't need any central point as it connects to other nodes directly (full mesh) it has built-in router that helps packets to route to the approperate destinations. there are two options for configuration: yaml file and if you want to have central configuration management it supports etcd. for the time being it supports symmetric encryptions and Linux platform.
Build
Given that the Go Language compiler (version 1.11 or greater is required) is installed, you can build it with:
go get github.com/mehrdadrad/radvpn
cd $GOPATH/src/github.com/mehrdadrad/radvpn
go build .
Docker
docker pull mehrdadrad/radvpn:latest
docker run --privileged -d -p 8085:8085 -v $(pwd)/radvpn.yaml:/etc/radvpn.yaml -e RADVPN_NODE_NAME=node1 mehrdadrad/radvpn:latest
Basic Config
With the default it tries to load config.yaml file individually at each node, but it can be configured to use same configuration through etcd. Once the configuration is changed, it loads and applies new changes by itself. Below yaml is a sample configuration:
revision: 1
crypto:
type: gcm
key: 6368616e676520746869732070617373776f726420746f206120736563726574
nodes:
- node:
name: node1
address: 8.121.55.10
privateAddresses:
- 10.0.1.1/24
privateSubnets:
- 10.0.1.0/24
- node:
name: node2
address: 84.12.92.45
privateAddresses:
- 10.0.2.1/24
privateSubnets:
- 10.0.2.0/24
Run
radvpn -config radvpn.conf
Configuration keys
- revision - the watcher works based on the revision number; once it increased, the configuration will be loaded immediately
- server
- keepalive - frequency duration of radvpn-to-radvpn ping to check if a connection is alive (default is 10 seconds)
- insecure - disable encryption (default is false)
- mtu - sets the mtu of the tunnel interface
- maxworkers - sets number of concurrent workers (read/write to/from tunnel concurrently)
- address - sets ip address and ports (format : ip:port)
- name - sets the name of the current node
- crypto
- type
- gcm - galois/counter mode
- cbc - cipher block chaining
- key - secret key
- type
- etcd
- endpoints - sets the etcd endpoints
- timeout - sets etcd endpoints timeout
- nodes
- node
- name - node's name
- address - node's external ip address
- privateAddresses - sets private address(es) on the tunnel interface
- privateSubnets - sets reachable subnet(s) from currect node
- node
Configuration with etcd
Run with etcd
radvpn -config radvpn.conf -etcd
Update etcd from yaml file
radvpn -update etcd -config radvpn.yaml
