I am trying to configure port forwording for a ftp server (192.168.20.20) in 857.
What I did
1) static port forwarding on port 20 and 21
2) enable acl to permit ftp and ftp-data traffic
3) enable ip inspect ftp
I assume this will work. The ftp server inside the network is just a windows ftp server.
I can ftp xx.xx.xx.xx public address without problem. But I can not list files. When i was connected, i did "sh ip nat translations". Both 20 and 21 have translations happening.
So what I did wrong? Any more port need to be opened or not?
Thanks
