Hi Gary,
I don't think the AS/400 will let you restrict connections via TCP/IP,
other than limiting the pool of virtual devices available and setting
system value QAUTOCFG to *NO. However, for the devices without an entry in
the host table, you won't be able to run any of the TCP/IP commands against
them by hostname, such as PING, TELNET, etc...
You can restrict access to the 400 by ports in the TCP/IP configuration.
You'll need to know which ports are used for TELNET and FTP, and then
restrict them to specific user profiles. I haven't used this feature, so I
can't really explain it in depth, but it might do what you're looking for.
It's option 4 from the CFGTCP menu.

Well, I put the host names in the Host Table on the 400 and now I can
see them.  Is there anything on the AS400 that will limit sessions
connecting based on the IP address or the host name of the PC?
Basically, can I restrict connections based on these parameters?
Gary
