Firewalls and Ports in Multi-Site (WAN) Configurations

Make sure your port settings are configured correctly for firewalls.

Each gateway receiver uses a port to listen for incoming communication from one or more gateway senders communication between GemFire sites. The full range of port values for gateway receivers must be made accessible within the firewall from across the WAN.

Properties for Firewall and Port Configuration in Multi-Site (WAN) Configurations

This table contains properties potentially involved in firewall behavior, with a brief description of each property. Click on a property name for a link to the gemfire.properties and gfsecurity.properties (GemFire Properties) reference topic.

not set Each gateway receiver uses a single port to accept connections from gateway senders in other systems. However, the configuration of a gateway receiver specifies a range of possible port values to use. GemFire selects an available port from the specified range when the gateway receiver starts. Configure your firewall so that the full range of possible port values is accessible by gateway senders from across the WAN.
