I'm trying to use active FTP with Chilkat. Here is the Output from a working FTP-Client (FlashFXP):

The interesting part is:

the client binds a port on my internal ip. Then its using that port with my external ip (my router is forwarding all requests to my internal ip).
all is working fine that way.
now to Chilkat FTP2: i cannot get it working with active mode :)
snipped from my code:
put_Passive(false);
put_Hostname(...);
put_Username(...);
put_Password(...);
put_Port(990);
put_HeartbeatMs(200);
put_SendBufferSize(4096);
put_AuthTls(true);
put_Ssl(false);
put_ForcePortIpAddress("80.130.210.228");
// explicit ssl !
put_AutoFix(false);
Connect();
GetDirCount();
but GetDirCount() is failing:

port binding is working, but the PORT command has to use my external ip

i already tried connecting without put_ForcePortIpAddress(). after connect i used put_ForcePortIpAddress(), but this wont work either.
Thanks in advance for any help
