I just skimmed through the code, and it seems to listen for both the

latter is for non-passive ftp, so yes it seems to be needed for both.
In LVS-DR (and LVS-Tun) when persistence is used (rather
than the LVS-NAT ftp helper) to link the ftp and ftp-data
ports, I would now assume that the ftp-data packets are
RIP->CIP. Presumably the return packets from the client are
CIP->VIP. Only ever having done this with a bench setup all
on private IPs, it now occurs to me that LVS-DR in a
production ftp server setup, is sending all its ftp-data
packets from the RIP.
Got any idea if this is right?
