Details

showopenports is a supportdata helper showing all Network-Ports (or port ranges) which are open to the internet.
It lists the virtual connection (PVC / VLAN) and the public IP each port is listening to and the target forwarding IP and port.

A similar command is showpcpitems and the very detailed showpcpinfo script.
A similar command showing ports open to the LAN is showportsopentolan.

showopenports is a query client using libavmfwnotify.so to send the EVENT_FWNOTIFY_EVENT_query avmipc event,
The responses attached to EVENT_FWNOTIFY_EVENT avmipc events are then collected and printed in human readable form.

fw 7.29 help:

root@fritz2:/var/mod/root# showopenports -?

usage: showopenports showopenports [options]

options:
  -?                 - print this help
  -f                 - follow all changes. (NOTSET)
  -D STRING          - switch debug logs on. (FUNC)

showopenports
showopenports -f

Examples

fw 7.29 DSL-Router with no manually opened ports:

root@fritz1:/var/mod/root# showopenports

52:          0 INI internet IGDPROBE TCP 192.168.178.1 9 88.69.XX.XX 9 "IGDPROBE4"
53:          0 INI voip VOIP UDP 192.168.178.1 7078-7097 188.100.XX.XX 7078-7097 "VOIP"
54:          0 INI voip VOIP UDP 192.168.178.1 5060 188.100.XX.XX 5060 "VOIP"

56: END

88.69.XX.XX is the public IP of the internet PVC.
188.100.XX.XX is the public IP of the VoIP PVC.

A * in the Mod column marks info from Supportdata-Probes, which will always stay incomplete.
A ** in the Mod column marks info from Supportdata2 probes, which by their nature will stay way more incomplete.
A - in the Mod column marks manual research, the Firmware then shows where the item occurs, not the Relation.
