thx for fast response
http://www.proftpd.org/docs/howto/FXP.htmlA client connects to two servers and forces them to talk with each other to avoid using your own bandwidth.
So one of the servers needs to be in active mode, the other one in passive mode.
I can only set my SPD8020 to use passive mode.
So the client sends a PASV command to my SPD8020 which should then return a PORT answer including
IP-Adress and Portnumber.
And here is the problem, the SPD8020 answers with the IP-address from inside my LAN (10.0.0.5) which the
other server can't connect to (because it is somewhere on the internet).
When doing such a FXP transfer from an outside FTP-Server to my Computer in my LAN running Filezilla Server, Filezilla Server answers with the external IP-Adress of my router.
Since I have your great new firmware for my SPD8020 I want to do a FXP transfer from an outside FTP-Server to my NAS without having my computer running.
I have added to screenshots:
The first one shows the NONWORKING transfer from outside FTP-Server to SPD8020 running fvdw. (PASV => 10.0.0.5,19,209) where the first 4 numbers are the internal ip ([L] answer from SPD8020).
The second one shows a WORKING transfer from outside FTP-Server to my Computer (PASV => 91.115.122.3,19,139) where the first 4 numbers are my external ip ([L] answer from Filezilla Server on my PC)
So the problem is, that the SPD8020 answers with its internal IP to the PASV command instead of the external IP-Adress.
best regards
