Re: IP Addressing. Was(CAE - client ip address)

["Jeffrey Silberberg" <jsilberberg@xxxxxxxxxxxxxx>]

Rod,

        In this case while the issue may be that the return packet is lost.
I believe the problem is routing on the source system.  In every IP Packet
is the Source IP and Target IP address of a the Packet. When the host
processes that Packet it uses the source address as the new Target for the
return Packet.

        If NIC2 is to be the target then it should also be the source.  To
force this add an explicit route to the system from a command line with the
route cmd, add function so that packets leaving the PC for the AS/400 and
it's subnet, will always leave from and return to NIC2.   By the way, if the
outbound packet from your PC is NAT translated by a router/firewall then the
AS/400 will see the adddress of the NAT box not the NIC regardless of which
NIC you leave on.
