Pureftp stopped working externally, unroutable address

[nsansari]

Hi All

So I've been running ISPConfig for a few years now. Currently on version 3.0.4.6 on top of ubuntu hardy.

Just found out that ftp is no longer accessible from external, though works fine internally through local ip address. It was configured for SSL when I initially installed the server a couple of years ago.

Following message in filezilla

Status: Connected
Status: Retrieving directory listing...
Command: PWD
Response: 257 "/" is your current location
Command: TYPE I
Response: 200 TYPE is now 8-bit binary
Command: PASV
Response: 227 Entering Passive Mode (192,168,1,205,156,255)
Status: Server sent passive reply with unroutable address. Using server address instead.
Command: MLSD
Error: Connection timed out
Error: Failed to retrieve directory listing

I have checked my router / firewall and nothing has changed and all ports that need opening are still open.

Any help much appreciated.
