[mpls-linux-general] iptables: Unknown error 4294967295

[J. N. <oc...@gm...>]

I'm trying to use iptables (version 1.3.5 mpls patched 1955 converted with
alien -scripts from rpm file) with a debian filesystem. When I launch this
rule (from various scripts of MPLS linux labs for example) I got this error:

A1:/etc# mpls nhlfe add key 0 instructions ds2exp 0xf 0x1e  0x3  0x0 0x0
exp2tc 0x3 0x1  0x0 0x3 push gen 2000 nexthop eth3 ipv4 10.0.5.3 | grep key
|cut -c 17-26
0x00000002
A1:/etc# iptables -A FORWARD -m dscp --dscp 0x1e -j mpls --nhlfe  0x00000002
iptables: Unknown error 4294967295

I've search for the error in google and I find: Try to recompile your kernel
source with CONFIG_IP_NF_TARGET_NETMAP=y
option in your .config file.

Whenk I looked mi .config file I realized that CONFIG_IP_NF_TARGET_NETMAP=y
is already set :S

Any ideas of what I have to llok or do?

Thank you very much
