Subject: | SoftIoc with Warning: Unable to clear IP_MULTICAST_ALL on Ubunto on WSL |

Hello,
I'm testing the current softIoc (EPICS R7.0.7.1-DEV Rev. R7.0.7-194-g7a65c001ce178f2547fa) on a Windows subsystem for Linux (WSL). The subsystem is Ubuntu 22.04.3.
When I start the softIoc I always get the following message:
Warning: Unable to clear IP_MULTICAST_ALL (err=92). This may cause problems on multi-homed hosts
Apart from this warning, everything seems to work fine.
Is this a WSl thing or a misconfiguration? How can I fix this?
Best,
Carsten
