Hello. i have used patch-o-matic to add the pptp-nat helper module kernel works fine, but userspace iptables tool fails with: "iptables: Invalid argument" i have seen a lot of posts and the solution is to compile the iptables-1.2.9 tools i downloaded a fresh copy from www.netfilter.org and run make KERNEL_DIR=mykerneldir it says: Extensions found: IPv4:recent IPv6:ah IPv6:esp IPv6:frag IPv6:ipv6header IPv6:hbh IPv6:dst IPv6:rt then i install. fine, but it continues with it's problems!!!! what can i do to compile the tools th right way?
