Ich habe eine Sicherheitsaushandlung Ausnahme in einem client mit WCF

Bekam ich eine Sicherheitsaushandlung Ausnahme in der client-Teil, wenn ich mich einloggen wollte in mein server auf einem anderen PC mit dem WCF-client und-server. Es funktioniert im lokalen Netzwerk, aber wenn ich den server online über das Internet mit der port-Weiterleitung und eine statische IP-Adresse habe ich diese exception im client.
