Re: Reverse Nat and ICMP packet

["Giant Sand Fan's" <rampxxxx@gmail.com>]

Hi,

I answer to myself.

The problem was that our hook that do the unpack was after -less
priority , higher number- that conntrack -both in prerouting- so in
the back the packet was a different one that the one conntrack saves.

The solution, just put with a priority NF_IP_PRI_CONNTRACK+1 .

Thanks.
