Hello. I rewrote some parts of the question, and illustrated it by a small ASCII picture to clearifiy the whole situation. I don't know why I haven't got a single answer, because over 350 people are subscribed to the list, so I hope that I'll get some help now. It would be grateful.
I use SocksCap to forward the iexplore cnnections to another port, a port on which stunnel listens.
On PC1, the client, stunnel is listening on port 500. So when I start iexplore.exe with SocksCap every connection goes to 127.0.0.1:500. PC1 connects to PC2, with connect = 192.168.0.2:123
On PC2, the server, stunnel listens on port 500. then is connects to the internet with connect = 127.0.0.1:80.
Here is the problem, stunnel doesn't connect to the internet over 127.0.0.1:80. I don't know why, but it doesnt.
---Stunnel.conf SERVER--- .. [inet] accept = 127.0.0.1:123 connect = 127.0.0.1:80
---Stunnel.conf CLIENT--- .. [inet] accept = 127.0.0.1:500 connect = 192.168.0.2:123

So the problem is that stunnel doesn't connect to the internet on PC2. I think i have to use something different than connect = 127.0.0.1:80 on PC2, but not sure.
The version of stunnel is 4.15 I'm using Windows.

Hi,
The normal etiquette on mailing lists is to not respond if you don't know the answer. Otherwise you would get hundreds and hundreds of useless 'I don't know' emails.
Perhaps no-one knows the answer or you aren't really describing the problem in a way we can understand.
I use SocksCap to forward the iexplore cnnections to another port, a port on which stunnel listens.
<snip>
I get the impression you want to browse the internet from PC1 but to have all the traffic proxied through PC2 (with the data being encrypted) , is this correct?
If not could you provide a brief (non technical) description of what you want and why. There may be better solutions to your problem than fighting with proxies and stunnel.
Regards
Ian
I would suggest changing the accept on the server to read accept = 123
As I understand the logic, the server is only listening on the loop back TCP address, not the public one.

Dear Unknown user (or LoopBack, whichever you prefer),
Contrary to your assertion that the server's stunnel connection is listening on port 500, the small piece of the stunnel.conf you have provided says otherwise.
---Stunnel.conf SERVER--- .. [inet] accept = 127.0.0.1:123 <--------- this means stunnel is listening on port # 123......not 500 connect = 127.0.0.1:80
Also, as you have specified the server's localhost IP address (127.0.0.1) on the accept, __no__ other computer can get to the stunnel server, as it is only expecting stunnel traffic from it's own virtual address, not any other computer.
If you setup the server as follows, it will accept stunnel connections from any computer on port 123 (or change this to whatever port number you want....at both ends) and send the traffic to its own port 80. I assume that anything hitting port 80 on this box is then "socksified" and forwarded elsewhere.
---Stunnel.conf SERVER--- .. [inet] accept = 123 < connect = 127.0.0.1:80
The client configuration looks fine to me.
I second Ian's comments.
Regards,
John Boxall
