Kann Host im Freifunk-Netz nicht über dn42 erreichen

[Marek Küthe]

Hallo,

ich möchte den Host
`10.119.2.225`/`fdc7:3c9d:b889:a272:9683:c4ff:fe41:aed`, welcher über
einen Ethernet-Anschluss an meinem Freifunk-Router (`ff3l-bandura`,
`1459c0cd1605`) angeschlossen ist, über das IC-VPN bzw. das dn42
erreichen - jedoch ohne Erfolg.

Bei dem Host handelt es sich um einen kleinen süßen OpenWrt-Router.

Von meinem dn42 Router:
```
$ ping -c 10 10.119.2.225

Beide nehmen den gleichen Weg über GW3.

Über IPv6 funktioniert es:

Könnte sich das jemand anschauen?
