[FRS-454] FusionReactor Firewall DNS and Static IP address rules (FusionReactor 8.0.x and above)

Introduction

This article applies to FusionReactor users running version 8.0.0 and above. Some users run FusionReactor behind restricted firewalls that do not allow all outbound connections. In this case, these users may need to add specific firewall rules to enable FusionReactor to communicate with FusionReactor Cloud.

This Technote covers configuring both the on-premise and cloud editions of FusionReactor.

If FusionReactor versions 5 -7 were previously installed, your DNS or static IP rules should still be valid, but your FusionReactor instances must be reconfigured.

To configure FusionReactor versions 5 to 7, see:

FusionReactor 5 to 7 On-Premise – https://fusion-reactor.com/support/kb/frs-425/

FusionReactor 5 to 7 Cloud – https://fusion-reactor.com/support/kb/frs-418/

PLEASE NOTE THAT THIS TECHNOTE IS VALID IF YOU ARE RUNNING FUSIONREACTOR 8.0.0 and above only

Using DNS Firewall Rules

To communicate with the FusionReactor infrastructure, each FusionReactor instance attempts to connect to the following services, which are identified by their DNS names:

• wss://cc.fusionreactor.io – port tcp/2804
• https://api.fusionreactor.io – port tcp/443

These services require outgoing firewall rules for FusionReactor to communicate with FusionReactor Cloud. SSL ciphers protect all communications.

If possible, the firewall should be configured with the DNS names of these services, since they can change in response to scaling events.

If the IP addresses are required, nslookup can be used to find their current values. Most services will yield two addresses: both must be added.

Using Static IP Addresses

If you are unable or unwilling to use the dynamic DNS rules above, we have provided a static IP address which can be used for all services.

• 46.137.127.35 – port tcp/443 and port tcp/2804

After enabling this firewall rule, the following -D options need to be applied to your JVM environment, to instruct FusionReactor to use the single address:

-Dfr.gcs.client.endpoint=wss://cc-static.fusionreactor.io:2804/
-Dfr.cloud.endpoint=https://api-static.fusionreactor.io

Locked-Down Environments

If you are using a non-standard Java security policy, you may have to add rules to allow FusionReactor to connect to these services. The form of these rules is:

permission java.net.SocketPermission “cc-static.fusionreactor.io:2804”, "connect, accept, resolve”;
permission java.net.SocketPermission “api-static.fusionreactor.io:443”, "connect, accept, resolve”;
