We Fixed UniFi's Slow PPPoE Performance by Offloading PPPoE to a Separate Device with Half-Bridge
Summary
The post details how ArcBox Labs improved UniFi PPPoE performance by offloading PPPoE to a dedicated device using a half-bridge (Zero IP Bridge). It explains why PPPoE on typical UniFi gateways bottlenecks, describes the offload architecture with OpenWrt, and provides implementation details, including hotplug scripts and DHCP-based IP handoff to hand a public IPv4 to the downstream gateway. The article also notes limitations and references real-world ISP scenarios.
