Subject: [stunnel-users] https to https proxy

Hi,

Our punchout vendor switched their site to only accept tls 1.2 over the weekend. Unfortunately our application will only support SSL.

We are using stunnel with other vendors but can control the inbound host name. This recent one is one we can't manage as it is the software provider.

I found a solution for doing https to https. I'm unclear how I get the first https traffic to route to stunnel as the initial call will be from the application will be to the external host..
Any thoughts on whether this would work for my situation?  Appreciate any thoughts..

[Tunnel_in]
client = yes
accept = host_ip:443
connect = localhost:54321

[Tunnel_out]
client = no
accept = localhost:54321
connect = externalhostname:443

Best regards,

Dan
