The first time you create a Gateway, you must download the Enterprise Service Gateway image file and register it with Identity as a Service.
If you allowlist outbound connections, you need to allowlist the following URLs for the Gateway to function:
● Your Identity as a Service account name (mycorp.us.trustedauth.com)
● entrust.us.trustedauth.com (for Enterprise Service Gateways upgrades)
● entrust.net (Entrust Certificate Authority)
Note: When you add an Enterprise Service Gateway, Entrust recommends that you use the defaults set by the appliance when you load it into VMWare. For the Enterprise Service Gateway to function, the minimum requirements are 2 x CPU, 4GB RAM, and 50GB of disk space. Adding more resources can help in high-end deployments.
For high availability, add a Gateway Instance to your Gateway. See Add a Gateway Instance.
