You can try, but I strongly doubt it. I suggest that you use a more
recent kernel, because the 2.4.18 kernel is *very* old (thus very broken).
Or you can try to apply the patches from the latest (but obsolete)
patch-o-matic tarball (patch-o-matic-20031219.tar.bz2) which can be
found in <http://ftp.netfilter.org/pub/patch-o-matic/>. I think you need
to apply submitted/01_2.4.19.patch up to submitted/05_2.4.23.patch to
your 2.4.18 tree. The last one provides the conntrack timeout sysctls.

Sorry, I do not know anything about this.
