# 1. Overview
|
|
|
|
## 1.1. Usage
|
|
|
|
The Program will listen for RoutingTable Changes and can translate the changes to a Wireguard-Interface.
|
|
|
|
It will detect the Peer to add the Route to using the Gateway from the Route-Entry.<br>
|
|
In case routes clash or cant be added to Wireguard, Warnings will be logged.
|
|
|
|
<br>
|
|
|
|
### 1.1.1. Examples
|
|
|
|
- Dynamic Routing with Routing-Protocols (e.g. OSPF)
|
|
- Interacting with Wireguard using the familiar Tools like `iproute2`
|
|
|
|
<br>
|
|
|
|
## 1.2. Install
|
|
|
|
### 1.2.1. Environment
|
|
|
|
Variable|Description|Default
|
|
-|-|-
|
|
`INTERFACE`* | Wireguard-Interface Name |
|
|
`FILTER_PROTOCOL` | Protocol to react on | All
|
|
`FILTER_TABLE` | Table to react on | All
|
|
|
|
*\* Required*
|
|
|
|
<br>
|
|
|
|
### 1.2.2. Docker
|
|
|
|
Depending on the needs, the Container can be run in `network_mode: host` to be able to access routing-tables and interfaces of the host.
|
|
|
|
Additionally the capability `NET_ADMIN` is required for interacting with interfaces.
|
|
|
|
<details><summary><code>docker-compose.yml</code></summary>

```yaml
|
|
version: '3'
|
|
|
|
services:
|
|
routingtabletowg:
|
|
image: ruakij/routingtabletowg
|
|
restart: unless-stopped
|
|
network_mode: host
|
|
cap_add:
|

|
|
```
|

</details>

|
|
### 1.2.3. Without Docker
|
|
|
|
Clone the Repository `git clone <URI>` and build the Program with `go build cmd/app`
|
|
|
|
Then you can run it with `./app`
