Getting Client Source in a rootless container
I ran into an interesting problem setting up PiHole on Podman. Pihole was not seeing the client IPS. This is due to how rootless containers work. Adding
--network slirp4netns:port_handler=slirp4netns forwards the source address. After this, I enabled Pihole listening on all interfaces. I am now able to group devices and have different block lists. Do note that this is slower, don't use the slirp4netns network unless necessary.
