We have a dev rke2 cluster deployed on a datacenter DC1 (3 masters , 12 workers)  
internal network for nodes (10.20.25.1/24)

We have also a 2nd datacenter called DC2 (3 masters, 6 workers)  
internal network for nodes (10.50.30.1/24)

Now, in order to allow to join the newly nodes from DC2 to the cluster created in DC1 , what are the network requirements ( firewall ports…and so on… ?)  
P.S. I just asked the net team to allocate a nat ip for each node in both datacenters.
