We upgraded Anya’s laptop to Fedora 40, and Skype has evidently moved from an installable RPM to a snap package. Which didn’t work with the firewall rules we built earlier in the year (video and audio calls would not connect); and, worse, nothing logs out. Looks like the netfilter kernel logging isn’t enabled

Enabled the logging:

echo 1 | sudo tee /proc/sys/net/netfilter/nf_log_all_netns

And, voila, we’ve got log records from nftables. And now Skype works … so I don’t know what to add. Sigh!
