FTP Bounce

[kiko]

Hello to everyone,

i have the following problem. I am trying to connect to a ftp server over flashfxp 3.0.2 (build 1045) registered, OS Win XP Prof. The connection is ok for one second. After this i lose it. If i connect to this server from a linux server without flashfxp then it works.

I get an error message on the firewall:
accept
and after one second
reject
ftp bounce

The logfile on flashfxp says:
