I am in process of setting up forwarders to push data from my corp network to splunk cloud instance. My data(machine data) sources are Tanium, Absolute DDS, Airwatch, AD....couple of more tools. If I am not wrong, it makes more sense to go for Gateway Forwarder. With that, my question is -
1. What is the sizing configuration for Gateway Forwarder I can consider?
2. From my reads I collect that, UDP 514[to forwarders] and TCP 9997[to indexer] are the ports that I need to open, is this correct?
3. Does splunk provides range of IP addresses for firewall to establish connection from our corp network to splunk cloud? or I am missing something?
