[mpls-linux-devel] About mpls-packet to ip-packet process

[刘磊 <orp...@ms...>]

Hi all:
I found that the packet which from ip stack to mpls stack in the ip_finish_output2 had passed POSTROUTING hook in netfilter.
BUT the packet from mpls stack to ip stack just use neighbour->output, which NOT hook in PREROUTING in netfilter.

In this way, if I do SNAT for ip packet and send into mpls stack, will NOT do Un-SNAT for the reply packet.

Is my understand right? How to solved it?
