Subject: HOW TRAVERSING CHAIN IN SNAT/DNAT
Date: Fri, 06 Dec 2002 10:06:16 +0100 [thread overview]
Message-ID: <3DF06888.10403@libero.it> (raw)
Hi list!
My question is:
I need to filter packet coming from eth1 (external lan) directed to eth0
(internal lan).
Packet for internal lan must be SNAT to reach external lan.
In this enviroment filter table see packets traversing FORWARD chain as
normal source and destination and i let it pass.
SNAT change source address with nat address indicated (3 ip address
configured on the box as alias of eth1) and then send packets.
When packets return as reply to my natted connection, the chain/chains
involved are:
only input ?
input and forward ?
only forward?
Someone can explain me this in detail?
Bye.
Giulius
