Remote AS/400 support over the internet

["Mark Villa" <markvilla@xxxxxxxxxxx>]

I know there are -other- appropriate ways with respect for firewalls, VPN
for example, but this case is a narrow scope.

Scenario
=========
You have a HOST "A" and 100 machines in the field. They all have TCP
internet connections and firewalls. No remote systems  have on site
administration that you may call on.

HOST- System A talks to REMOTE System B just fine using SDLC over a modem.
On Host System A ports and any other admin chores are not an issue.

Now, REMOTE System B upgrades and decides they don't want to use dial-up
SDLC anymore.

REMOTE System B can telnet through the firewall to HOST System A just fine.

The PROBLEM:
=============
I can not figure out how to start pass thru or telnet sessions "FROM" Host
System A once System "B" has established TCP contact/sessions with HOST
System A, without performing admin at the 100 remote sites.

What I want to do is establish a 2 way path, like dial-up SDLC does,
initiated at REMOTE System B.

The real problem I am running into is not knowing their internet address
ahead of time for definition in HOST System "A" host table, for APPC over
TCP using *ANYNET on HOST System, that would not be an option, too much
admin. There has got to be an easier way.
Ideally I would say, okay Store #204, run this command using my IP address
xxx.xxx.xxx.xxx, this will allow me to start a session on your system and
look at your job log for you. This also keeps security /positive control
under the remote site umbrella.

I have seen reference to dynamic sessions, but, not sure enough to proceed
with investigating even more.


Thanks -very- much for any pointers. P.S. - a host package to answer this
would be okay, but any remote changes are not possible. This would mean it
is an ongoing chore with new stores, etc.
