1) Allow our outgoing IPs
You can find the outgoing IPs for OGO log export in My Profile > Log Export.
If you have protocol filtering in place, make sure to whitelist them with the export port defined in your OGO configuration.
2) Mutual TLS
You can download our certification authority in My Profile > Log Export > Logstash.
Place this certification authority on your Logstash server.
Then, adapt your configuration as below:
input { tcp { ... ssl_certificate_authorities => ["/path/ogo-logexport-ca.pem"] }}
