Hello all: I'm trying to configure an IPv6 Firewall in a Linux machine, (Red Hat 9 with kernel 2.4.20), following the steps stated in http://www.tldp.org/HOWTO/Linux+IPv6-HOWTO/x2083.html#AEN2085. I've downloaded iptables 1.2.8, changed KERNEL_DIR variable and typed make and make install (since make pending-patches and make patch-o-matic are no valid statements) without problems. However, when I try to setup the kernel I can't find some options in IPv6: Netfilter configuration like REJECT target support, or AH/ESP match support. Anybody knows what can be wrong?. Best regards. Javi Garzon
