I ran the command as you wrote on a CBQ RaQ and it worked OK.
The RaQ used the Strongbolt Installer sb01.06-03.iso
What does 'lsmod' yield?
My lsmod before runing the cmd =
[root@localhost ~]# lsmod
Module Size Used by
iptable_filter 1344 1
ip_tables 9720 1 iptable_filter
x_tables 6788 1 ip_tables
After running the command -
[root@localhost ~]# lsmod
Module Size Used by
ipt_REDIRECT 928 1
xt_tcpudp 1984 1
iptable_nat 5668 1
ip_nat 10636 2 ipt_REDIRECT,iptable_nat
ip_conntrack 30828 2 iptable_nat,ip_nat
iptable_filter 1344 1
ip_tables 9720 2 iptable_nat,iptable_filter
x_tables 6788 4
ipt_REDIRECT,xt_tcpudp,iptable_nat,ip_tables
I do have a RaQ built with an earlier version of the Strongbolt
installer that gave the same error, you experienced.
The CBQ-RaQ that works has;
[root (at mark) localhost ~]# locate iptable_nat.ko
/lib/modules/2.6.16i586/kernel/net/ipv4/netfilter/iptable_nat.ko
/lib/modules/2.6.9-55.0.9.EL/kernel/net/ipv4/netfilter/iptable_nat.ko
The CBQ-RaQ that doesn't work does have;
/lib/modules/2.6.9-55.0.9.EL/kernel/net/ipv4/netfilter/iptable_nat.ko
But does not have;
/lib/modules/2.6.16i586/kernel/net/ipv4/netfilter/iptable_nat.ko
So it may be you need the missing kernel module...
