PPTP NAT and iptables compilation

PPTP NAT and iptables compilation

[ihernandez]

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?

The new compiled iptables is at /usr/local/sbin/iptables
when i try it says:

/usr/local/sbin/iptables -A POSTROUTING -t nat -o eth0 -j MASQUERADE
iptables: Invalid argument


i'm not sure that patch-o-matic is really doing the right job with the
iptables patch. i mean, the user space patch.

Are you sure the command you've run afterwards is the newly-compiled version, 
and not just the old one sitting somewhere in your path?

What does "ls -al `find / -name iptables`" show ?   (Those are single 
backticks around the find command).

Antony.

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.
