Ruby gem to generate configuration for wireguard to build a mesh VPN of multiple nodes. Supports configuring gateway devices, keepalives, IPv4 and IPv6 subnets.
It's usable, however I'm sure there are bugs. Please report if you find any.
Maybe. In my limited testing it works reliably.
Run wgconf example config.yml, which will generate an example configuration with 3 nodes. Remove the private keys to generate new ones. Don't touch the psk_map section, it will be automatically generated and kept up-to-date. When you're done, run wgconf generate config.yml --outdir configs. The tool will write all configuration files in the configs directory.
Don't add private keys manually, the tool will do that for you. Give your nodes descriptive names. It will also generate unique preshared keys for each node connection.
Your YAML configuration contains private and preshared keys for all of your nodes. Keep it in a secure place.
What's up with persistent keepalive?
You must set persistent_keepalive in your YAML configuration to a number greater than 0 to use this feature. Wgconf will automatically set up keepalive where it makes sense (one of the nodes have client_only set to true and the other one doesn't).
Please do.
