I'm looking for advice configuring Linode firewall for my Enhance cluster.
I know there's better firewall management coming natively in Enhance, wanting to get something in place n the interim.
I've applied to one server in the cluster. The only issue I've seen so far is a "Failed to load" error in the Enhance Network info panel. I'd appreciate anyone's experience / advice?
My current config:
Default inbound policy: DROP.
- All Enhance Servers in cluster, All ports, TCP/UDP, ALLOW (servers all communicate with each other freely)
- My IP, port 22, TCP, ALLOW (SSH in)
- Any IP, port 80, TCP, ALLOW
- Any IP, port 443, TCP, ALLOW
- Any IP, port 21, TCP, ALLOW (FTP)
- Any IP, port 30000-31000, UDP, ALLOW (Passive FTP)
- Any IP, port 53, TCP/UDP, ALLOW (DNS)
Default outbound policy: ALLOW
Any IP, 22, TCP, DROP
Any IP, 25, TCP, DROP (No email sent from any server)
Any IP, 3389, TCP, DROP (No outgoing RDP connections)
