Smart FTP and shared LAN connection

When I make my LAN connection shared (to let my home network computers access LAN), SmartFTP fails to connect to any FTP-server. As soon as I disable LAN connection sharing (even without rebooting) everything works just fine. Is there anything to do about this? Thanks in advance.
SmartFTP version is 2.0.996
OS: WinXP Pro + SP2

Looks like noone knows... Could anyone just try to do the same thing with the connection sharing and tell me whether it works or not, please?
