Hi,
Current stunnel implementation is based on peer-to-peer communication and it cannot be used in the environment where a management server wants to talk to multi-site server (i.e. an instance of server running in different sites).
Multi Tunnel support for Stunnel enables a Management Server to communicate with Multisite Server. But it requires extending Stunnel with a new protocol whereby Management Server & Client Stunnel Process communicates.
1. The new stunnel conf for multi tunnel (keeping backward compatibility) look like
[singleTunnelServiceName]
accept = aport
connect = ip:cport
[serviceName]
multitunnel = yes
accept = 1234
connect = ip1:5678,ip2:5678,ip3:5678,...ipn:5678
