latest version of the kernel
# uname -r
2.6.18-53.el5.028stab051.1
# iptables -t nat -L
iptables v1.3.5: can't initialize iptables table `nat': Table does not exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.
# lsmod | grep nat
<nothing>
# modprobe -l | grep ip_nat

In short, I am trying to use NAT so that I can have several virtual machines using one IP, but it seem like the NAT table just doesn't work.
When I look on google, I've seen others with the same issue, but no obvious fix.
