Why SoftEther VPN

The mechanism that it is used is DNS. For example, if my JID is bill company. The service domain is usually specified by the user the first time they attempt to log into Jabber. Though, the service domain can also be administratively assigned in the jabber-config.

Once the service domain is known, the Jabber client will go through the sub-process of Service Discovery. In a properly implemented solution, this query should return one or more records that point to your Expressway Edge or VCS-E cluster. Assuming everything is configured correctly and fully operational, the Jabber client will attempt to establish a TLS connection to one of your Edge appliances.

Once the client establishes a TLS connection to port on the Edge appliance, the user credentials are authenticated. At this point, the proxy connection is established and the client will start downloading configuration information from the UCM cluster. This configuration information is used to complete the service registration phases.

Registration requests are sent to the Edge appliance, which is then proxied through the Core appliance to the UCM cluster node s. All of these procedures are performed from the client perspective. This step is fairly straightforward.

If the client can resolve the UDS records then the Jabber client will never attempt to connect to the Edge. This troubleshooting step is a little more involved. Therefore, you need a way to generate Base64 values such as openssl. The API calls also are built using specific application hostnames in your environment. So, you will need to have that information handy. Let's start with the base64 conversion process. On a Mac OSX system, you can use openssl to generate the base64 string.

That is a pain, so you may be better off using this online encoder: We are now done with the funky base64 strings yay!
