Based on your description, I am fairly certain that you need only one tunnel
(IPSEC in tunnel mode) definition with the endpoints defined (on each
firewall) as:

Secure Subnet = Gateway=
Secure Subnet =  Gateway=

With these endpoints for the single tunnel, the expected results would be:

1.  Anybody behind the Raptor firewall will be able to telnet transparently
to the outside interface of the Gauntlet firewall and have the packets

2.  Anyone on the Gauntlet itself could telnet to the inside of the Raptor
firewall to the network and have the packets encrypted.

3.  Anyone behind the Gauntlet should be able to telnet to if
those packets are routed to the Gauntlet firewall, which should then
transparently proxy them (I think it supports transparent access through the
telnet proxy)and send them back down the stack and through the tunnel for
which it matched.

Let me know.
