Explains port restrictions when setting up Vultr firewall rules, noting specific reserved port ranges for internal Load Balancer operations
When configuring firewall rules on a Vultr Load Balancer, ports 65300 to 65310 are reserved for internal Load Balancer operations. These ports cannot be used for traffic forwarding or included in custom firewall rules, as they are required for internal communication and management tasks.
All other ports may be used in firewall rules, subject to protocol and backend configuration requirements.
