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]
;client = yes
accept = 8008-->port used by sfdc client to connect to TIBCO server
connect = localhost:8009 -->Tibco server that's running
cert = stunnel.pem
2016.11.23 08:31:56 LOG7[118]: Service [SFDC reverse proxy test] started
2016.11.23 08:31:56 LOG7[118]: Option TCP_NODELAY set on local socket

2016.11.23 08:31:56 LOG3[118]: SSL_accept: Peer suddenly disconnected
2016.11.23 08:31:56 LOG5[118]: Connection reset: 0 byte(s) sent to SSL, 0 byte(s) sent to socket

2016.11.23 08:31:56 LOG7[118]: Service [SFDC reverse proxy test] finished (0 left)

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
