# PolyculeNetwork

PolyculeNetwork is a drop-in solution for infrastructure mutualisation, when subnets to mutualize use the same ip ranges. It is based on nftables, wireguard and python.

## Installation

### Dedicated VM/LXC/server (recommended)

Install dependencies:
```
# Debian
apt install python3-poetry wireguard nftables
```

Install python dependencies :
```
poetry install
```

### Docker

On the host, you'll need `docker` and `docker-compose-plugin`.

Clone this repo, edit the `docker-compose.yml` file to suit your needs, and set `config/config.toml` to reflect you infrastructure.

You will need to create an empty `config/dnnsmasq.conf` for the first launch (it will be generated by the main container, but the file needs to exist).

Launch `docker compose`, get the ip address of the polyculenetwork container, and set manual routes via this ip:

```bash
ip route add <translated remote network> via <container ip>
```

Finally, run on the host

```bash
sysctl -w net.ipv4.ip_forward
iptables -A FORWARD -j ACCEPT
```

You will need to run these commands after each restart of the host machine.
