[stunnel-users] More questions on RDP and port forwarding

I did read through the archives but I cannot determine how to get Stunnel
working through the firewall. Here is what I wish to do:

1. Tunnel Windows Remote Desktop through stunnel.
2. I wish to connect from home to work; I have access to the firewall at
work.

Here's what I've done:

1. Installed stunnel on Windows XP at home and at work. I have self-signed
certificates and am using verify = 3 (on both computers). Cacert.pem has
the CA cert, the work cert, and the home cert in a single file. The
server-cert.pem has the work computer's key and cert while the
client-1-cert.pem (home computer) has it's own key and cert.
2. Stunnel at home has client = yes, stunnel at work has this commented
out. Stunnel at work will become a "server" where multiple clients connect
via stunnel and that single computer makes multiple RDP connections.

Client (home) computer has

[rdp1]
accept = 4391
connect = <work outside interface IP>:44391

Server (work) computer has

[rdp2]
accept = 44391
connect = <work computer name>:3392

If I try this at work from within the corporate network (change the client
connect string to the stunnel server's IP or hostname), then everything
works fine. However, once I try from outside the work network, nothing
works. Firewall is a Watchguard SOHO 6tc and I have a inbound rule
permitting 44391 and directing it to X.X.X.52 (the stunnel server). I also
have other rules allowing RDP (on port 3392 for instance) directly to the
computer I wish to control and those rules work. Essentially, RDP directly
through the firewall works but stunnel through the firewall does not. I
assume there is no traffic destined for .52 on 44391 because the log file on
the server (with debug = 7) only shows the startup sequence and port binding
(netstat -a shows I am listening on 44391). I also tried this at home on my
Juniper 5XT and was unsuccessful. Please help.
