I am currently running xubuntu 12.10 with lampserver and proftpd. I have an issue where the ftp works from the home network, but does not work from outside.

I routed it fine through my router because the website does work, its just the ftp that is giving me problems.

I get the following from filezilla:

If anyone can help me, I would greatly appreciate it.

Thank You,

I get the same output connecting to my proftp server, right up to where the PASV command is issued - so it looks like something in your config is not allowing PASV transfers, or you have PASV transfers routed to closed ports and the server drops the connection. –  douggro May 23 '13 at 17:50
