I've asked about ports currently in listening state, not just any port list.
And for an example, "/ip services" doesn't list ports for DNS service (53/tcp, 53/udp) provided by MikroTik device.
Substitute '192.168.88.1' with the LAN IP address of your router. You can perform the same check from outside the network on a cellphone hotspot as well using your WAN IP address, but beware that Android hotspots show false positives for port 80 and something else I can't remember off the top of my head.
