# 1. Overview
|
|
|
|
The program will convert IPv4-only wireguard-interfaces to IPv6. It converts and adds the Address of the Interface and AllowedIPs-Entries with optional filters.
|
|
|
|
IPv6-Adresses are generated based on the IPv4-Adress.
|
|
|
|
Beware: This program needs `NET_ADMIN` privileges for setting Adresses and to access the wireguard-daemon.

|
|
2. Save at an appropriate location e.g. `/usr/bin/local/wg-ipv6-converter`
|
|
3. Make executeable: `chmod +x /usr/bin/local/wg-ipv6-converter`
|

## 3.2. Examples
|
|
|
|
### 3.2.1. Netbird
|
|
|
|
Netbird is at the moment only IPv4-compatible, with this program running where necessary, some basic IPv6-setup can be archieved.
|
|
|
|
```bash
|
|
INTERFACE="wt0" ./wg-ipv6-converter
|
|
```
|
|
Or using a systemd-service based on the example:
|
|
```bash
|
|
[Unit]
|
|
Description=WireGuard IPv6 converter for netbird
|
|
BindsTo=netbird.service
|
|
|
|
[Service]
|
|
Type=simple
|
|
ExecStart=/usr/local/bin/wg-ipv6-converter
|
|

|
|

|
|
StandardOutput=syslog
|
|

|
|
|
|
