Further to this I did find an issue with the iptables loopback and IPv6 which I corrected. It still wasn’t caching the packages.xz from either the local machine or others in the local net. I ended up adding a refresh pattern for .gz and .xz which seems to cache them now. I am using 1440 20% 1440 which I thought was fairly conservative.
