The logic in tcp_timer() was inverted. fwd_out
should expose the host
ports in the ns. Therfore it must read the ports on the host and then
bind them in the netns. The same for fwd_in which checks ports in the
ns and then exposes them on the host.
Note that this only fixes tcp ports, udp does not seems to work at all
right now with the auto mode.
Note that for UDP there's no periodic scan,
"auto" just checks bound
ports when pasta starts:
-u, --udp-ports spec
Configure UDP port forwarding to namespace. spec is as described
for TCP above, and the list of ports is derived from listening
sockets reported by /proc/net/udp and /proc/net/udp6, see
proc(5), when pasta starts (not periodically).
Ok this makes sense then, is there a bug to track this? Because without
it auto mode for UDP is useless for my Podman use case.
