Foolishly I updated to 1.2.1 this week and immediatly hit a problem. I connect to a FTP server on my lan remotely by using a dns alias to resolve my public IP and then have port forwarding to permit access to a raspberry pi running a small FTP server. This has always worked fine. As soon as 1.2.1 was applied I got a peculiar problem. A remote connection could logon but then just when it was about to retrieve the directory listing (I use FileZilla client) it would timeout. Initially I though about PASV and maybe it was something to do with the client trying to open additional ports but changing that did not help. Eventually I had to change the timeout setting on the client to 40 seconds. It's unclear what's causing the problem but its definately linked to 1.2.1
