Re: [mpls-linux-general] fc8.mpls 1.961 - iptables error : invalid argument,

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

I'll post here the reply that I sent yesterday. In case that could help
anyone.

Hello Lee Kye Hwan,
The error that you mention in 99% of the cases are because a bad kernel
configuration. The only way that I avoid this error is installing a correct
version of iptables with the correct version of kernel (in my case I used
mpls 1955 version of iptables with kernel 2.6.18.1).
I fixed that error with that but now I've got an other error related to
iptables too (like I post in the mailing list)


PS: I think that I have already fixed my error of unknow argument applying
the policy in the mangle table instead directly with -A forward


regards
