Hallo,
ich habe 2 Netzwerkkarten in meinem Rechner. Auf der ersten Karte ist meine eigene IP Adresse 192.168.100.198 und auf der zweiten 192.168.101.5.
Wenn ich nun einen Broadcast sende, wird auf beiden Karten mit der selben source IP (der von der zweiten Karte) gesendet. Gerüft habe ich das mit Packetyzer siehe unten.
Ich benutze Delphi 7 pro und habe es mit den Indytools und mit der UdpSockUtil von Narses ausprobiert, bei beiden das selbe Resultat. Ist das vielleicht ein WinSocket Fehler.
Kann mir da einer weiter helfen?
Heiko
