Missing IPv6 default route in routing table after wings was started for first time #107
Description
I have an issue where after the first start of the wings daemon no IPv6 connections can be made anymore, because the routing table misses the default route.
I made an output of the first time the software is started.
Output of ip -6 route before first wings start

As you can see, the pelican0 route was added and the default route was removed. Therefore no IPv6 connections can be made outside my network.
This issue was reproducible on a Debian 12 (clean install, and following documentation on wings install) as well as on a OpenSUSE Leap 15.6 installation (which is not listed as supported in the documentation).
IPv4 connections still work.
