Dear friends,

I've a requirement to access SAP EP through a public IP. In our scenario SAP Web Dispatcher is located in DMZ and rest all SAP systems are in MZ.

We have registered a domain name (couple of weeks ago) and binding has been done with the public IP address. Natting has been done between Public IP and private IP of SAP Web Dispatcher. When we are trying to access the portal now using public IP address it doesn't bring any page rather gives error:

This site can’t be reached

202.100.196.244 refused to connect.

ERR_CONNECTION_REFUSED

Below is our Web dispatcher config file contents, kindly suggest if there is something wrong with this:
