RE: query on ip configuration

KSI,

What you're describing strikes me as very appropriate, providing that
they are executing the telnet/ftp commands from their iSeries session.

If you find that your users can suddenly access the internet from their
PC's when they have a connection to the iSeries, then your server is
functioning as a gateway.  Check the IPDTGFWD (IP Datagram Forwarding)
parameter on your TCP attributes.  If it is *YES, change it to *NO.  Use
the CHGTCPA (Change TCP Attributes) command.  The default for this
parameter is *NO.
