Redundant DNS configurations provide fallback options if primary DNS servers become unavailable. Configure multiple DNS servers in network settings ensuring continued name resolution during outages affecting individual servers. This redundancy maintains connectivity even when specific DNS infrastructure experiences problems.
Firewall Configuration
Properly configured firewalls protect crypto mining hardware while permitting necessary connectivity. Allow outbound connections to mining pool servers and blockchain nodes while blocking unsolicited inbound traffic. This selective approach provides security without impeding legitimate mining operations.
Connection tracking features in modern firewalls enable stateful packet inspection ensuring only responses to initiated connections reach bitcoin mining machines. This protection prevents exploitation attempts from external attackers while maintaining transparent operation for outbound mining communications.
Regular firewall rule reviews ensure configurations remain appropriate as operational requirements evolve. Periodically audit rules removing obsolete permissions and adding protections for newly identified threats. Security configurations require ongoing maintenance rather than set-and-forget approaches particularly as network threats continuously evolve.
Load Balancing
Multi-WAN configurations distribute crypto mining rig traffic across multiple internet connections improving aggregate bandwidth and reliability. Load balancing routers automatically distribute connections across available links optimizing utilization. If one connection fails, traffic shifts to remaining links maintaining partial connectivity reducing revenue losses during outages.
Intelligent load balancing considers connection characteristics assigning traffic based on latency, bandwidth, and reliability metrics. This optimization ensures bitcoin mining machines use best-performing connections rather than simply dividing traffic equally across available options. Advanced algorithms maximize overall network performance through strategic traffic distribution.
