The following shows that the ftp helper module (ip_vs_ftp) is in fact
loaded.
[root@lb1 ~]# modprobe -l|grep ftp
/lib/modules/2.6.17.11/kernel/net/ipv4/ipvs/ip_vs_ftp.ko
/lib/modules/2.6.17.11/kernel/net/ipv4/netfilter/ip_conntrack_tftp.ko
/lib/modules/2.6.17.11/kernel/net/ipv4/netfilter/ip_conntrack_ftp.ko
So why would it not be working? Network traces on the client machines
show the FTP-DATA connection is not being NATed.
Here's the output from ipvsadm if it helps:
[root@lb1 ~]# ipvsadm
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP extrovert.mycharts.md:ftp wlc
