I have upgraded iptables in my kernel 2.4.10
I use RH 7.0
I compile new bzImage and modules.
When I restart system I get this info:

[root@point /home]# iptables -L
iptables v1.2.4: can't initialize iptables table `filter': Module is wrong version
Perhaps iptables or your kernel needs to be upgraded.
[root@point /home]# iptables -t NAT -A PREROUTING -s 10.0.0.0/24 -j MASQUERADE
iptables v1.2.4: can't initialize iptables table `NAT': Module is wrong version
Perhaps iptables or your kernel needs to be upgraded.


Why?
What Must I upgrade in this system?
I use newest iptables' rpm
Please help

check to make sure the ipchains module isn't loaded. if it is ... rmmod it and then try doing some iptable rules.

ipchains is not loaded......
other idea?

[root@point /root]# ipchains
ipchains: no command specified
Try `ipchains -h' or 'ipchains --help' for more information.
[root@point /root]# ipchains -L
ipchains: Incompatible with this kernel
[root@point /root]#

upss..... sory

system said : ipchains module is not loaded
when I wrote rmmod ipchains

I suppose that you need make a new kernel. ALL modules of iptables are necessary bild INSIDE kernels. It's a simplest way.
Kernel must be 2.4.X, 3d numeral not essential.
