I don't believe that's correct. The 2.4.x kernels are going to be
backwards compatible with ipfwadm (2.0.x) and ipchains (2.2.x) kernels.
Here's a portion of Documentation/Configure.help that shipped with
2.4.0-test7:
ipchains (2.2-style) support
CONFIG_IP_NF_COMPAT_IPCHAINS
This option places ipchains (with masquerading and redirection
support) back into the kernel, using the new netfilter
infrastructure. It is not recommended for new installations (see
`Packet filtering'). With this enabled, you should be able to use
the ipchains tool exactly as in 2.2 kernels.
If you want to compile it as a module, say M here and read
Documentation/modules.txt. If unsure, say `N'.
ipfwadm (2.0-style) support
CONFIG_IP_NF_COMPAT_IPFWADM
This option places ipfwadm (with masquerading and redirection
support) back into the kernel, using the new netfilter
infrastructure. It is not recommended for new installations (see
`Packet filtering'). With this enabled, you should be able to use
the ipfwadm tool exactly as in 2.0 kernels.
