I understand it’s the spec not a bug.

Yes, I check that reverse lookup fails as you pointed out.

The reason why I’m using the slight old version is to write a magazine article introducing nftables. It’s easy for readers to install the version I checked with RPM or archive like 'nftables-0.3’.
Anyway, I’ll test the latest before sending a report to this ML.

Best Rio.
