I haven't tried it myself since I am in between upgrades, but why not try out pom-ng? I am almost positive that you need: pom-ng + iptables from CVS in order for things to work fine. I've tried various combinations of userspace 1.2.9+ and POM, but they have regularty broken since POM-ng has been developed. The iptables module in CVS doesn't support the old POM. ihernandez@xxxxxxxxxxxxxxxxx wrote: > 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?
