This is wireguard script configuration for a intermediate public server to interconnect two sites.

So you can reach LAN 2 from LAN 1 and vice versa but LAN also reach Internet directly without using VPN Server. The VPN server is only used to reach each LAN.

This is not a newbie tool, this is just a helper to configure my VPN server. If you do not know about networking, linux & vpn (wireguard) this tool maybe, it is not for you. Anyway if you know and you think you can do a better job to give a good documentation for everyone I accept contributions.

Install wireguard-tools to generate the configuration.

1. Install using whatever package manager is in your Linux system the packages wireguard & wireguard-tools
2. Configure .env.dist and save as .env
3. Generate the config

./generate_wg_config

1. Install brew & wireguard cli

! { command -v brew &> /dev/null; } && /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
! brew list wireguard-tools &> /dev/null && brew install wireguard-go wireguard-tools

2. Configure .env.dist and rename to .env

mv .env.dist .env

3. Generate the config

./generate_wg_config

1. Install WSL and use in WSL as Linux

If you have generated the configuration files in the final Wireguard Server you can set up Wireguard as a service by using:

./start_wg_as_service

If you want to test or you want to execute wireguard manually you can by using:

echo "Starting wireguard"
./start_wg

To stop:

echo "Stoping wireguard"
./stop_wg

Install wireguard in the terminals (phone or computer) that would be also a peers (outside of the LANS) and use the configuration files for those peers.

In the LANs, install the wireguard or use wireguard-go dockerized using the configuration file.

If you use Wg in your gateway it must know how to get any direct local network so you should be able to get those networks that router must know how to reach and route to other networks through the VPN networks. Any special routing configuration can be needed so you need some networking knowledge.

Please do not use issues to ask about any other configuration that is not implicit with wireguard or any linux server configuration.

After generating a configuration you can add a new peer by using ./add_new_peer command.

See usage with ./add_new_peer --help.

IMPORTANT: You need to know the ip you will give to the peer and configuration must be as when generated (minimum the public & private keys & configuration for server, normmally called wg0).

You can use these scripts by adding them to PATH in your .bashrc (or equivalent file), execute in the path of these files locally:

echo "PATH=\"\${PATH+:\$PATH:$PWD}\"\n" | tee -a ~/.bashrc &>/dev/null
. ~/.bashrc
{ grep -q "$PWD" ~/.bashrc && command -v add_new_peer && echo "Now you can execute wireguard-site-to-site scripts"; } || echo "[FAIL] wireguard-site-to-site PATH could not be found"

PRs are accepted to improve the scripts, tools and documentation. Anyway, whatever contribution should keep the main target which is connect P2P two or more LANs.

If you need some help with wireguard the official webiste (witepapper) is very good reference but you can also access to sample wireguard configurations and documentation here:
