This week: mwan3 load balancing on K1, RISC-V networking tips, and K1-8G product spotlight.
Weekly Tech Digest - Week 31, 2026
This week our community discussed RISC-V networking, OpenWrt configuration, and multi-WAN load balancing on the SpacemiT K1 platform.
Featured Discussion: mwan3 Load Balancing on K1
A user asked about configuring mwan3 for dual WAN load balancing on the K1 RISC-V platform running OpenWrt 23.05.
Key Takeaways
- mwan3 is fully compatible with OpenWrt 23.05 on RISC-V
- nftables (fw4) is the default firewall — use the nftables-compatible mwan3 version
- iptables-nft provides backward compatibility if needed
- K1 8-core X60 handles multi-WAN routing at near line-rate
- Physical isolation via dual RGMII + YT9152S switches is recommended for security
Configuration Summary
The setup involves:
- Installing mwan3 and luci-app-mwan3 packages
- Configuring WAN1 and WAN2 interfaces on separate Ethernet devices
- Creating balanced policy with equal weight members
- Verifying with mwan3 status command
