Hello, im facing this problem:
dmz → orange → Ubuntu 20.04 with filezilla-server. Ip: 192.168.2.2 and gateway 192.168.2.1
green zone → Windows 10 with filezilla-client. ip 192.168.0.2 and gateway 192.168.0.1
I want to connect from ftp client in green zone with ftp server in orange/dmz.
Im able to ping from green to dmz.
$ping 192.168.2.2 ( from machine 192.168.0.2)
But i open filezilla-client as said in green windows, and put the quick connection to connect to filezilla-server in dma/orange ( ip 192.168.2.2):
192.168.2.2 user; joe password:*** port:21 …and i got error connection refused…
As from green to orange communication is allowed…im missing something ? Or i ve to add some firewall rules ? Port 21 is closed ?
