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

OK, I took my configs, my certs, etc. and put them on two boxes in the lab - then I ensured I could use stunnel to connect using VNC. I then put a NAT box (Linksys BEFSR81) between the two and configured the Linksys to provide port forwarding. I then reconnected and everything worked first time. Therefore, I can only assume that either port-forwarding is misconfigured on my Watchguard SOHO 6tc -or- that the Windows firewall is causing problems (neither lab box has a firewall running). I'll keep you posted on what I find. Thanks. Richard My original post: 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. Richard

Craig, Thanks. Are you advising that I put "client = yes" in the service declaration rather than the main configuration? I already have "client = yes" on the client side (in the main configuration) and that line commented out of the server's configuration (I assume the default is client = no). When I review the log on the client computer, I can see where it times out waiting on a response from the work firewall's outside IP address. I do not see any connection attempts on the server side and both stunnel instances (client and server) have debug = 7 and logging to stunnel.log.

I'm very much a newbie to stunnel
by Harmon, Paul 26 Nov '07

Hi Guys, I'm very new to Stunnel. In fact I have no experience with it what so ever. My situation is this: I have server program and a client at the moment which know nothing about SSL. Yet the powers that be insist that my two machines, if they must use sockets, do so using SSL. After reading through the distribution, I found this very interesting program called Stunnel which sounds like it might solve my problem quite well. From what I've read so far, I gather this program can be used as an SSL wrapper for my server and my client. Would some kind soul please help me with the configuration process (the configuration file) so that my client and server can be safe and secure? My server uses a port which I have chosen (really quite arbitrarily). Basically I need the server to listen on that port and wait for incoming data which it will processs and in most cases not even reply. With normal sockets this is a no-brainer since Steven's book outlines it very well. If I understand the documentation I've read so far, Stunnel adds the encryption layer on top of that which I need. So how do I configure and invokestunnel in this environment? Sorry for stupid questions at the moment I just lack examples like this and confidence in using the program. Thanks, Paul

Certificate management
by Koenraad Lelong 23 Nov '07

23 Nov '07

Hi, Since a few months I'm playing with stunnel. Last month I installed a stunnel at a customer. This week he reported he could not connect any more. After testing here I discovered the CA cert had expired. I made this myself and I didn't see that it's only valid for one month. I made new certificates making sure they are valid for longer than one month, so this is solved for now. My question : are there good documents about management of certificates ? I'm specially interested in renewing the certificates. Regards, Koenraad Lelong.

some newbie questions
by Lluís Forns 23 Nov '07

23 Nov '07

Let me first explain what I want to do in order to see if stunnel is what I need: I have some laptops around the world and I want to let them login in my intranet. The login is versus a Samba server. So more or less the connection would be: Laptop (running winXP) --- router --- internet --- router --- linux ssh server(port 22 open) --- linux samba server Could stunnel help me achivieng this? any hint of how? I have read the documentation, but I am a little lost. thanks -- <http://www.escoltesiguies.cat>*Lluís Forns - Tècnic Informàtic * *Servei d'Informàtica* *Minyons Escoltes i Guies de Catalunya (MEG)* *Telèfon:* 93 590 27 00 *Fax:* 93 590 04 92 *www.escoltesiguies.cat* No m'imprimeixis si no és necessari.

Re: [stunnel-users] Stunnel and Outlook Web Access Problems

I see that you have client = yes in the config file. When client = yes is set outside the service block, it becomes a global setting that tells all the services that it should tunnel that they are clients and not servers. If you specify the client = yes within a service eg. [pop3s] client = yes accept = 995 connect = 110 then stunnel knows that the specified service alone is a client. What I recommend is that you disable the client = yes in the global area and change you config file to something like this: I have removed the comments to shorten the config for explanation: socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 CRLpath = crls CRLfile = certnew.pem debug = 7 output = stunnel.log ;client = yes [https] accept = 443 connect = 192.168.0.5:443 TIMEOUTclose = 0 Try using this as your config and see if it works or not.

Dan _____ From: Craig Sent: Mon 19/11/2007 1:34 AM To: stunnel-users(a)mirt.net Subject: Re: [stunnel-users] Stunnel and Outlook Web Access Problems OWA rewrites the URL when you log in and I have found that it causes problems when doing that with a Stunnel connection. What I think might be happening is that your initial connection says http://server.tld/ then when you log in OWA rewrites the URL to https://server.tld/ What I think is happening is that your stunnel is listening on port 80 and when you log in, OWA changes the listening port in the browser to port 443. Try running the listening server (stunnel server) to listen on port 443 instead of port 80 and see if that fixes the problem.

I set stunnel to listen on port 80 (localhost) and then connect to myserverip on port 443. I get the login screen but can go no further after I Enter my credentials and Click OK. Checking the stunnel log screen it shows that a connect has been made? I don't understand why It won't connect any further?? OWA is on Exchange Server 2003 and I am using Windows XP SP2.

NFS over stunnel
by Andy Wettstein 19 Nov '07

19 Nov '07

Hi, I wrote a document about how I am running NFS over stunnel. Using some firewall rules I was able to eliminate most of the complications for using secure NFS. It could probably use more detailed explanations, but the scripts I am using are all there. It still kind of in test phase, but I am currently mounting my home directory using stunnel. I haven't really noticed much of a speed problem in day to day activities. https://w3.physics.uiuc.edu/physwiki/doku.php?id=pcs:unix:nfs_over_stunnel Please send any questions you might have. -- andy wettstein unix administrator department of physics university of illinois at urbana-champaign
