RE: Access from behind the firewall

["Urbanek, Marty" <Marty_Urbanek@xxxxxxxxxxxx>]

William,

We recently had a thread similar to this titled Network Pasthru. Some of us
believe that you could use Anynet plus IP Forwarding to route TCP/IP traffic
from your 270 to your 720 via the SNA link. Since no 5250 passthrough would
be used, no additional interactive workload on the 270 would be incurred.

Subject: Access from behind the firewall


Hello All!

I have a problem that I hope someone has solved.

The setup is an internal network running TCP/IP to the firewall to a =
model 270 (a web page server).  SNA is used as the communications =
protocol from the 270 to the back-end model 720 (development machine and =
data server to the 270).  The model 270 is running minimal interactive =
processing load.  I can access the model 270 directly anywhere in the =
world because I know the IP address and have appropriate access.

My question is:   How can I access the model 720 via the 270 without =
kicking off additional interactive load?  I'd like to passthru =
immediately from the 270 to the 720 seamlessly, but this appears to =
require interactive work on the part of the 270.

I do not want to expose the 720 directly to the firewall because that =
will nullify the advantage of using SNA between the boxes.

The ideal result will let me have access to the 720 anywhere in the =
world, but I have to go thru the 270 to do it.

High level concepts or the nitty-gritty details will both be =
appreciated.  If there is documentation somewhere, I'm willing to read!

Thanks in advance...
