Решение - подгрузить модули на ноде openvz:

# modprobe nf_conntrack_netbios_ns
# modprobe nf_nat_ftp
# modprobe nf_conntrack_ftp

+подключить модули в конфиге контейнера:

# vi /etc/vz/conf/17750.conf
IPTABLES="ip_tables iptable_filter iptable_mangle ipt_limit ipt_multiport ipt_tos ipt_TOS ipt_REJECT ipt_TCPMSS ipt_tcpmss ipt_ttl ipt_LOG ipt_length ip_conntrack ip_conntrack_ftp ipt_state iptable_nat ip_nat_ftp"
# vzctl set 17750 --netfilter full --save --setmode restart
