Hi all, ty in advance for any help.

I have a service that I can connect to a destination over stunnel, but I am not able to get the ack I expect.

Internal sending service => stunnel => external listening service

I think the problem may be that the firewall is blocking inbound traffic.

I need to specify a specific port for the firewall team to open so that traffic can get back to my stunnel service, since every time stunnel starts it will be making a connection from a different port on the external facing side of the SSL encapsulation service/pipe/whatever you want to call it!!

What would be the best way to configure stunnel for that scenario. I can see the INETD mode but that does not seem to be what I am looking for, I can also see the transparent option but not sure what that really does.

Any advice appreciated.

Regards

Stewart
