On: Podman 4.2.0

Did they fix the IP propagation issue with Rootless networking ? It makes it largely useless when the Proxy is also a container.

on Docker you can force it to use Slirp, but its slow and doesn't support IPv6.

You could detect the source IP address by using the command-line option:

--net=slirp4netns:port_handler=slirp4netns

See https://github.com/containers/podman/discussions/10472#discu...

Shouldn't it also be possible to detect the source IP address if you use socket activation? (I haven't tried it out, though).

But that's using Slirp, which has its own problems.

Ok, I understand your concern about Slirp.

Regarding the other idea: I've now tested it and verified that it works. The remote address is available when running a socket-activated container with rootless Podman.
