#731 closed Bug report

Multiple IPs on one NIC -> active FTP problem

Reported by: anonymous Owned by:
Priority: normal Component: Other
Keywords: Cc: Tim Kosse
Component version: Operating system type:
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.
