Hi all, I have a cluster of 5 nodes connected to each other and now I want to use UFW to deny any external incoming traffic into them but i will allow each node to access between themselves. Which ports should i open (pb_port,http_port,solr,...)? I connect via pbc but i may need more ports open i guess.
A configurations like this (assuming is node_1): ufw default deny incoming ufw default allow outgoing ufw allow 22 --> SSH (private keys) ufw allow from <load_balancer> to any port 443 --> HTTPS (API that talks with Riak locally via Python client) ufw allow from <node_2> to any port <port_numbers> ufw allow from <node_3> to any port <port_numbers> ufw allow from <node_4> to any port <port_numbers> ufw allow from <node_5> to any port <port_numbers> Thanks! Alex
