ICS Port Mapping (WinXP Internetfreigabe)

[Dani]

Hallo zusammen,
Ich frage mich, ob es möglich ist, mit Delphi auf folgende Einstellungen zuzugreifen:

Bild ist im Anhang zu sehen.
(Hier sollte ein Bild der freigegebenen Ports der WinXP Internetfreigabe zu sehen sein)

Laut MSDN (Link) wird dazu ein COM-Interface benutzt. Kann ich aus Delphi heraus auf diese Schnittstelle zugreifen?

Beste Grüße,
Dani

Geh mal auf Projekt -> Typbibliothek importieren..., dann wählst du "NetCon 1.0 Type Library" aus und klickst auf Installieren. Somit hast die ganzen Interface-Deklarationen schon mal.

Meine Güte, all die Möglichkeiten...
Danke vielmals!

Habs aufgegeben, bin an der Enumeration gescheitert :(

Naja, jetzt muss halt das JavaScript Beispiel herhalten... benötigte Zeit, um 10 000 Ports freizugeben: 8,3 Stunden :mrgreen:

Code:

ICSSC_DEFAULT = 0;

ICSTT_NAME      = 0;
ICSTT_IPADDRESS = 1;

// from netcon.idl
//NCM_SHAREDACCESSHOST_LAN = 8;
//NCM_SHAREDACCESSHOST_RAS = 9;

NAT_PROTOCOL_TCP = 6
NAT_PROTOCOL_UDP = 17

// from netcon.idl
NCCF_SHARED     = 0x0100;   // Connection is shared
NCCF_FIREWALLED = 0x0400;   // Connection is firewalled
