  • These are the network requirements for a secure working installation:

    • Internal resources (configured from the CloudGen Access Console) can only communicate with the internal leg of the Envoy Proxy.

    • The Envoy proxy has an internal leg and an internet-facing leg.

    • The Internet-facing leg needs to expose the configured CloudGen Access Proxy port.

    • For High Availability mode (HA), the Envoy Proxy must be placed behind a layer 3 round robin load balancer.
