Hi,
I would like to know where exactly reverse mapping(packets coming from
outside to the internal network) is done in the case of SNAT? From the
netfilter documentation, it seems to be done in the POST_ROUTING hook.
Is it true?
Logically I would expect the packet to be reverse mapped in the
pre-routing state itself. Why would one want to reverse map it in post
routing? I am sure I am missing something. Could anyone please
enlighten me?
Any help would be appreciated.
Regards,
Vinay

I think you are talking about what seems to be the connection
tracking, once a packet match a rule in the nat table it will use that
rule until the connection is closed and in both sides.
