ESS + FlashFXP = only passive mode functional?

Hello!

I renewed my license in November and at the same time upgraded from NOD32 to ESS. Today when I tried using FlashFXP to connect to my school account I get a "list error". I tried 10+ different major FTP sites like Adobe, Microsoft etc and noone works!

If I manually change them to use "passive mode" then everything works. Can ESS be causing this behaviour?

Thanks!

 

Yes, ESS causes this. You have to open Port 20 for incoming Data-Connections. This is part of the (active) FTP-Protocol.

Could you please be more specific? TCP/UDP etc?

 

You have to open TCP Port 20 on the client that initiates an active FTP connection. -> your computer

Is there any reason why you need an active connection? Why not stay with the passive type?

 

I tried this but it didn't work:


- FTP: Where the protocol is TCP and direction is outbound and remoteport is 21 Allow it

- FTPDATA: Where the protocol is TCP and direction is inbound and remoteport is 20 Allow it

-PASV FTP: Where the protocol is TCP and direction is outbound and remoteport is 1024-65535 Allow it

 

Replace "TCP 20 inbound Remote" with "TCP 20 inbound Local" (the other tab) ... the ftp-client opens port 20 on YOUR computer so that the server can connect to your computer on this port.

 

Tried changing it but I still need to use passive mode...
