As if the TCP is less secure? Not necessarily as the TCP sockets here most likely live in a private network between the two containers: you run `podman network create example` and then `podman run --net=example whatever`. This creates an internal network (e.g., 10.0.0.1/10) over which the pods communicate. Only if you want to expose some port would you use `-p` flag to expose it to host LAN, which you then redirect to WAN.
