Network Address Translation (NAT) and the WebSpeed distributed configuration
Network Address Translation, or NAT, is an Internet standard that supports one set of Internet Protocol (IP) addresses for external traffic and a second set of addresses for internal use. A router translates these IP addresses between network domains, hiding internal addresses and generating globally unique, routable addresses. NAT, and IP Convert, are general forms to mask IP addresses, shielding this information from the Internet. In this manner, the NAT process helps promote more secure connections between clients and WebSpeed.
OpenEdge and WebSpeed support NAT in a distributed configuration arrangement through a registration process. The value you select for the Registration Mode indicates how the WebSpeed broker identifies its hostname when the WebSpeed broker registers with its controlling NameServer. When a client application attempts to connect to an application service on a host machine that the WebSpeed broker supports, the hostname information is passed to the client application, provided that the information can be authenticated.
The specific value you set up for the Registration mode depends on the connection arrangement you want. The following procedures identify and describe the Registration mode values.
You can make a client connection through a NAT firewall using OpenEdge Management or OpenEdge Explorer. Alternatively, you can make a client connection through a NAT firewall using ubroker.properties file.
