Multiple IPs on one NIC -> active FTP problem
|Reported by:||anonymous||Owned by:|

|Operating system version:|
System: Windows Server 2003 with multiple IPs defined
on the NIC
Default IP: x.x.x.100
Additional IPs: x.x.x.110, x.x.x.120
Filezilla server listening on IP x.x.x.110
Client connection and authentication is successful.
when the client requests the directory listing in
ACTIVE-ftp mode, the server answers NOT with the source
IP x.x.x.110, but with x.x.x.100!
The server should only use the IP it's listening on to
communicate with the clients!
(otherwise it confuses firewalls, nat-ting devices ...)
When using PASSIVE-ftp, the server uses the correct IP.
