You appear to have the inverse of most scenarios. The majority of these such
cases involve connecting IP hosts to SNA servers, typically via TN3270. The
Cisco router is capable of handling this scenario well. However, the inverse
is more of an issue, as it rather turns the whole thing on its head. The
only solution I can think of is that the client/server IP activity must
occur using IP end-to-end, which would mean configuring IP on the end
stations. Is this feasible? A bridging solution is wholly out of the
question, as that would simply take the SNA traffic and dump it out on a
TCP/IP network, where it wouldn't be understood. I rather suspect that if
you are unable to have the end stations communicate with the server directly
over TCP/IP, you will be forced into a custom solution, which is probably
going to be very expensive, or, possibly worse still, be faced with the fact
that it simply cannot be achieved. I really can't see how this could be
configured on the Cisco router, as it is not really capable of performing
backwards translation in order to talk to an IP server. As I said before, it
would normally be the other way around, with IP clients running something
like IBM Personal Communications (TN3270 client) to talk to a S/390 through
a TN3270 server. Even host-on-demand wouldn't help here.
So, to sum up, short of a special custom solution, I cannot see you being
able to achieve the desired result using what is currently available from
either IBM or Cisco, though I am really not fully qualified to speak with
great authority any further on the subject. I would suggest speaking with a
consultant to find out more.
Good luck in your endeavours.
