One longstanding problem with Podman is that your rootful containers may loose network connectivity after a while. For many users it is not be obvious what is causing such problems. Netavark configures NAT and port forwarding firewall rules. When another process is deleting our firewall rules the containers will loose connectivity. One such process is…

I am pleased to announce new versions of netavark and aardvark-dns. There were lots of dependency updates (libraries) for each project. Netavark now also has preliminary support for DHCP and MacVLAN as well as the ability to write your own plugins. Good stuff!

It is coming together nicely — Update When we released Podman 4, we also released a new “network stack” that in large part was provided by netavark. At that time, a couple of features were missing for us to achieve parity with the previous network stack based on CNI Plugins. One key missing feature was…
We are pleased to announce the release of aardvark-dns and netavark v1.4.0.

In the aardvark-dns release, the key new function was provided by commit 01a9f18f411b9766e6476fc53c395844aa3cb62e which is titled add support for…
