I've chatted with the client aome more and have a better idea of what's actually happening.... 1) an end user TN3270s to a specific IP address, 2) the Cisco router then connects the TN3270 cleint to a VTAM Netview Access Services application (NVAS) [The magic incantation "VTAM LST" was
also heard at this point of the discussions....:-)] 3) the end user can choose to be connected to another application, runnin g on another host someplace else. 4) VTAM then routes that connection through a 3745-170 unit that is attached to the z/VM system. I'll take a look now at the exit DB mentioned and see if I can't figure i t out. There are no plans to bring in Linux on zSeries (for EE) or to repla ce the 3745 box......just the two Cisco routers. Have a good one. DJ
