Hi,

    Can I create IP spoofing by following scenario?

Internal client -> Firewall /w NAT (NAT:209.0.0.1) -> Internet ->
www.somewhere.com -> Internet -> Target server (209.0.0.1)

    I issue "PING www.somewhere.com" from the internal client.  The packet
will reach www.somewhere.com, then the reply packet will go to the target
server.

    The source IP of outgoing packet will be translated to 209.0.0.1 by NAT.

    If I have a tool to perform NAT and control the NAT port, I can attack
others?

Carl
