Pasta-networked rootless Podman container gets Connection Refused with the host's public IP
by jklaiho＠iki.fi 28 Jun '23

28 Jun '23

Hi; I previously asked this on the Podman mailing list, but I'm not sure if the issue in question is a feature of Podman or Passt (or both), and I got no replies from the Podman list, so I figured I'd try here as well. We're running some rootless Podman containers set up to use Pasta 2023_03_29.b10b983 for networking. One of the containers needs to access the host machine port 443 with its public IP address, but this causes a Connection Refused error. Any other public IP is accessible normally. This is specific to the containers; the host has no problem accessing itself with the public IP. The containers are set up with systemd generators (quadlet), with networking configured very simply: "Network=pasta:-t,auto,-T,auto" Podman has a --map-gw option useable with Pasta that seemed like it might help, but it didn't. "Network=pasta:--map-gw,-t,auto,-T,auto" fails like this at container startup: Error: failed to start pasta: Port forwarding mode 'none' conflicts with previous mode "Network=pasta:-t,auto,-T,auto,--map-gw" started the container fine, but did not fix the Connection Refused error. Apparently --map-gw just isn't the right option here. I don't know if the inability to contact the public IP is a feature of Podman or Pasta, but I'm hoping you're able to at least narrow it down for me. Is there a workaround on the Pasta side? Thanks in advance! - JK Laiho
