Introduction
Your EdgeVis Server has two IP addresses that it must know and communicate with others:
Internal IP Address
The address of your server on the local network. This usually never changes, and is communicated with other servers in your cluster so that they know how to communicate with each other.
External IP Address
This is the address that your server shares with encoders and viewing clients on how to communicate with the server. It is often different to the internal address, as your server is usually placed behind a firewall that you have opened to the internet.
There are two features that require an external IP address to be properly configured:
Multi-server resilience
The server will automatically build a list of all external addresses in your cluster, and pass this list to your encoders/viewers - they can then attempt to use any of the available addresses to connect to the server.
Single Sign-on (SSO)
As part of setting up SSO you will usually have to provide your Identity Provider with a valid callback web address - as a security feature, this must match the real-world live URL supplied by the server when your user logs in. The external IP address is used to help build the URL and if this doesn't match then SSO will fail.
How do I see/change my current external IP address?
The external IP address was set by the user who originally installed EdgeVis Server. To see what it was configured to, you must:
Login to your server as a System Administrator, then select All server settings -> Multi-site resilience. If it is not enabled, click the Enable multi-site resilience button.
Note: this does not actually require you to utilise more than one server, but it is simply a setting that allows the capability to be used in future. Your existing server will continue to function as it did before.
Your Multi-site resilience page will now show the state of your servers and databases:
Click on the first server listed under Servers in this cluster.
On the resultant page, click the Edit this server's addresses button. This will show you the current setting:
You can, if you wish, change the current setting or add additional addresses. Note that making a change will restart the server service, with a short interruption to your users.
