Comment 3 for bug 1453180

I notice that the ip_vs_ftp module is used by nf_nat. Does this mean that FTP mangling cannot happen without the firewall?

I really don't want to enable to the Linux firewall ... all of this is behind a Cisco firewall with restrictive ACLs, even though I'm using public IPs on this machine.

root@lb1:~# lsmod | grep ftp
ip_vs_ftp 13079 0
ip_vs 136629 2 ip_vs_ftp
nf_nat 21841 1 ip_vs_ftp

If I have to enable the firewall, then I will need help configuring it. In addition to being a load balancer, this machine also serves as a router -- the only way to access the back-end servers, even directly by private IP, is by routing through it.
