How to enabled ipt_MASQUERADE?

[opc31199]

Hi,

I configure /etc/vz/vz.conf the iptable line whit:

IPTABLES="ip_tables ipt_REJECT ipt_tos ipt_limit ipt_multiport iptable_filter iptable_mangle ipt_TCPMSS ipt_tcpmss ipt_ttl ipt_length ip_conntrack ip_conntrack_ftp ip_conntrack_irc ipt_LOG ipt_conntrack ipt_helper ipt_state iptable_nat ip_nat_ftp ip_nat_irc ipt_TOS ipt_MASQUERADE"

later I restart vz service:

/etc/init.d/vz restart

and this message say tha the module ipt_MASQUERADE is skipped

Warning: Unknown iptable module: ipt_MASQUERADE, skipped

How to enabled ipt_MASQUERADE?

Any idea?

Regards
