lvs-dr and shorewall

[merdan.atajanov@xxxxxxxxxxxxxx]

Hello, I try to secure my director box by installing shorewall on it.
Everything is running alright, except ftp. When I use ftp I am 
redirected to one
of the server, but I cannot list or send files, cannot establish data
connection.
If shorewall is stopped, everything works perfect.
Does anyone know what rule should I add to the shorewall running on the
director machine?
