Juris,
        After using NS/Router for a few weeks, it was obvious that the PC's
took a noticeable performance hit.  I found it to be both slow and
unreliable.
I can't say that I noticed a big difference on the AS/400 side, however
I have
heard that some shops were experiencing as much as a 30% performance
degradation.
I would recommend using straight TCP/IP.  Its fast, reliable and easy to
configure.
