When attempting to access my FTP server over the internet, the connection times out when the client sends the LIST command:
Status: Connection established, waiting for welcome message...
Response: 220 (vsFTPd 2.1.2)
Command: USER anonymous
Response: 331 Please specify the password.
Command: PASS **************
Response: 230 Login successful.
Command: OPTS UTF8 ON
Response: 200 Always in UTF8 mode.
Status: Retrieving directory listing...
Response: 257 "/"
Command: TYPE I
Response: 200 Switching to Binary mode.
Response: 227 Entering Passive Mode (xxx,xx,xx,xxx,255,147).
Error: Connection timed out
Error: Failed to retrieve directory listing
Note: the x's replace my WAN address
However, when being accessed from a LAN the server simply sends the list, and the client is able to browse the server directories just fine.
Thanks in advance,
