Re: Network Pasthru

Alex,

This sounded close until I noticed that it was SNA over TCP/IP. What I probably
need is TCP/IP over SNA but I don't want to have to load tcp onto the V3R2M0
system. I think what I am trying to do is TCP/IP to the V4R4M0 (soon V4R5M0) and
APPN through it to the V3R2M0 over SNA.
