[stunnel-users] newbie config not running

[fuzzy_4711]

Hello list.

I am new to stunnel and do have some problems to get it running.

The server is a WinXPSP2 behind a router. The router has port forwarding
enabled for port 9999 to the stunnel server (4.21). On the same box a
vnc server is running on port 5900 which I like to tunnel. Firewall is
opened. The netstat -a -n shows the server listening on the desired port
(9999).

My server config looks like that:

cert = stunnel.pem
;key = stunnel.pem

; Some performance tunings
socket = l:TCP_NODELAY=1
socket = r:TCP_NODELAY=1

; Workaround for Eudora bug
;options = DONT_INSERT_EMPTY_FRAGMENTS

; Authentication stuff
;verify = 2
; Don't forget to c_rehash CApath
;CApath = certs
; It's often easier to use CAfile
;CAfile = certs.pem
; Don't forget to c_rehash CRLpath
;CRLpath = crls
; Alternatively you can use CRLfile
;CRLfile = crls.pem

; Some debugging stuff useful for troubleshooting
;debug = 7
;output = stunnel.log

; Use it for client mode
;client = yes

[pop3s]
accept  = 995
connect = 110

[imaps]
accept  = 993
connect = 143

[ssmtp]
accept  = 465
connect = 25

[VNC Server]
accept = 9999
connect = 5900

The client side is a linux box with config setting:
client = yes

[VNC Server]
accept = 5900
connect = 9999

I turned on debugging and stunnel.log seems to be okay - no error messages.

But I am not able to get an connection.

What am I doing wrong?
