PegaCHAT question: Should XMPP port also be externally available to the browsers used by customer?
The document (https://docs.pega.com/premises-chat-server-installation) for the on-premises chat implementation says on Page#3 "This port must be externally accessible to the browsers used by CSRs who will provide service using chat." The default is port 5280
Question: Should this XMPP port also be externally available to the browsers used by customer? or only between the the CSR browser and the CHAT server?
