Somewhat interestingly:

$ ./pasta --config-net -- sh -c 'sleep 0.05; ping -c1 88.198.0.161'
PING 88.198.0.161 (88.198.0.161) 56(84) bytes of data.
64 bytes from 88.198.0.161: icmp_seq=1 ttl=255 time=0.593 ms

--- 88.198.0.161 ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 0.593/0.593/0.593/0.000 ms

$ ./pasta --config-net -- sh -c 'ping -c1 88.198.0.161'
ping: connect: Network is unreachable

...but that's not the same that happens with Podman, I'm still
debugging that.
