I've Meraki MX64 FW version 16.16 and we have a problem connecting to an external public FTP server through ftp command of windows.
Outbound connection from LAN of Meraki on port 21 of external FTP server connects successfully but data connection doesn't work (if I type DIR the connection hangs).
I know that FTP passive mode isn't supported by ftp.exe windows client and also that passive mode can be activated on external FTP server, but I don't have control on external FTP server.
I read that outbound connection of this type requires a particular NAT traversal implementation (in ex. ALG ).
Does MX NAT supports correctly fix up NAT for active mode connections to allow the return traffic?
Thanks in advance
