I was thinking of the BeagleBone Black as another option.  I personally
have no experience with them.
  A Telnet client is a standard tool; if it doesn't
come pre-installed
 it's just a matter of installing the relevant package. 
Yep.
Configure things with DE-9 / DB-25 to 8P8C adapters, a la. Yost, and
you've got a capable device.
It could even be possible to configure the gateway device to inherently
work both directions.  Allow outbound connections /and/ inbound
connections.  The devil is in the details of configuring the software to
do (at least) what you want it to do.
