There are other tools for performing port forwarding with less overhead (I believe tappipe is one), although I make use stunnel to do this extensively.

In order forward a secure connection from one port to another is a two step process with stunnel:

A sample configuration segment would be:

[SFDC reverse in]

client = no

accept = 8008

Hi, there.

I'm no stunnel expert, but here's my $0.05 (we have no pennies in Canada anymore ;-) ):
- I would try including the key as well as the cert in your stunnel config
- I would enable debug on the openssl s_client call to see if it will indicate why it is reseting. Same with your SFDC client to get more info.
- Question: is the "WARNING: can't open config file" message below indicative of a permissions or path problem?
- Question: Is the stunnel cert and key compatible with the TIBCO server's certificate? They need to be using certs generated from the same key source, don't they?
- You might want to fix the SSL version in the stunnel config file (i.e. sslVersion = TLSv1.2)

Good luck with your debugging.

HI all,

 

There is a problem we have currently connecting tibco client to SFDC sever via TLS v1.2 and that’s solved by using stunnel in client mode. And the communication from SFDC client to tibco server applications w.r.t TLS V1.2 I am unable to solve using stunnel. Below is the configuration in stunnel in server end to divert the traffic from 8008 to 8009, can you help here with the logs is the stunnel configuration is correct or there any missed/need to alter.

 

[SFDC reverse proxy test]

debug=7

;client = yes

accept = 8008àport used by sfdc client to connect to TIBCO server

connect = localhost:8009 àTibco server that’s running

cert = stunnel.pem

PFB the openssl snap shot looks odd

C:\Program Files (x86)\stunnel\bin>openssl s_client -connect localhost:8008 -prexit -showcerts

WARNING: can't open config file: /devel/win32/openssl/openssl.cnf

CONNECTED(0000016C)
