  • 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...
