It should actually be removed. Apparently, even RH 2.4 kernels with the ipsec code are broken: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=126611 See also: http://mailman.ds9a.nl/pipermail/lartc/2004q4/014307.html And the thread at: http://marc.theaimsgroup.com/?l=linux-netdev&m=109582576330019&w=2 So I guess you're better off trying something like the NETMAP target in iptables.
