We have created the Service REST in Pega, Authentication is enabled in Service Package rule. Tested the same in development environment, it's working as expected with respect to request and response point of view. 

We are unable to get REST Response from Postman (Google Chrome) why?

Any restriction at Firewall /  Proxy level to reach to Pega application REST Service from Postman? (OR) Do we need to do any security configuration setting for allowing postman requests?

Thanks,
