Hi guys, I'm new to stunnel and I'm looking for a way to run stunnel on a single port. Then based on the client certificate, proxy that connection (in clear) to a different IP:port.
If this something I can do with stunnel or am i barking up the wrong tree so to speak.
Any help would be a appreciated guys.
Cheers Ric

Server Name Indication support is already on the TODO list: http://stunnel.mirt.net/?page=todo_sdf http://en.wikipedia.org/wiki/Server_Name_Indication
Please let me know if you would like to sponsor the implementation of this feature.
Best regards, Mike

In this case the client would always connect to example.com on port 7000 for example. Then based on which client cert is used to connect the client would be forwarded to a different IP:port. I'm not sure thats what you mean with Server Name Indication.
my example:
both client 1 and client 2 connect to stunnel.example.com:7000
client 1 would connect and may be proxied to client1.example.com:9000
client 2 would connect and may be proxied to cleint2.example.com:6789
If possible this would be configured in the stunnel.conf file on the server.

Dear Richard,
Yes, that's precisely what I mean by Server Name Indication support in stunnel.

I read your email once again and I discovered that I had misunderstood you. Stunnel only implements authentication based on client certificates and not authorization. I'm sorry for confusion.

Not exactly what you're looking for, but it may be worth to mention that I've written a patch to redirect to a user that doesn't successfully authentify:
http://ftp.nluug.nl/networking/stunnel/contrib/evil.patch
A small explanation is available at the beginning.
