IP forwarding for elastic search cluster

Hi Elastic Team,

I am new to Elastic search. Please help me to understand this .

I have elastic search cluster with 3 master nodes and 5 data nodes also
3 logstash nodes .

(Elastic search nodes are running in VM's and logstash and kibana are running as docker containers )

Does this setup required ip forwarding enabled ? if yes what is the reason.

If i disable ip forwarding will it effect my cluster communication or data shipping ?

Any replies would be appreciated ..!!

Regards,
Krishna

What do you mean by IP forwarding here?

If we have elastic cluster setup as mentioned above. do we need IP forwarding enabled to communicate between nodes ? or other network hosts to ship data ? is there any dependency on below config ?

In linux here is the configuration /etc/sysctl.conf

net.ipv4.ip_forward=1

I can't find a reference to it in the docs, and I have never been aware of needing that. Unless anyone else with better understanding chimes in, I would suggest it's probably not necessary.
