We have a Cisco 4700 ACE Router/Load Balancer which sits on the outside of our DMZ.
In addition we have that forward network traffic in round-robin mode to 2 IIS servers. We have opened up SSL port 443 to the router from outside and set-up a SSL certificate on both IIS servers with the correct bindings to the certificates. The certificate is valid and the Root certificate is also trusted.
Whenever when we connect to the router, we receive TCP packets on 443 on the server receiving the request, but then the connection stops and in the web browser get "No data received".
Is it even possible to have SSL working on servers behind the router or does the SSL need to be terminated at the point the request comes in?
If the current set-up is ok, what is the issue?
Just to give some extra information, when we trace the packets into the IIS server, the last packet before no packets are sent is a HTTPS RST, ACK packet.
