## IPv6 journey
When I first used WireGuard with my new OpenBSD vm on all my devices, i noticed
that my some of my requests towards specific services were not working anymore.
For instance, I spent some time trying to reach :
- gitlab.com
- github.com
- ungleich.ch
In fact, I had hard times accessing these services only when I was connected to
my WireGuard server (which has IPv4 and IPv6, with some default wireguard
settings I carried with me for six months), and only through my system dns.
In fact I figured out that it happened only when I was under an IPv6 capable
router.
## Solution
Adding IPv6 subnet to server and clients configuration files.
## Next
Enable IPv6 routing in the domain controller, for a single-ip usage.
## BSD routing
The default routing configuration does not allow my domain controller to reach
the **ungleich's infrastructure and services**.
```
echo "\!/sbin/route add -inet 185.203.112/24 185.203.114.1" >> /etc/hostname.vio1
```
Then I want to be able to access IPv6 only services when I'm using my wireguard
server (right now it only allows to force IPv4 to the client).
