Network Configurations 

IF SAWS is installed on a server where outside access is restricted to specific URLs , in that case we need to whitelist following addresses on network so that saws can communicate over the network to dvsum web app


3) In order to access SAWS from DvSum Web App, Contact SAWS Server System Administrator to open the configured port on Firewall/Network level. This port is mentioned in the file (Step 5). By default it is set to 8183.
