Could you build this?
No Implementing a PPPoE half-bridge solution to bypass hardware acceleration bottlenecks involves low-level Linux networking, kernel packet routing, and deep telecommunications protocol engineering.
What it would actually take: The solution requires configuring an intermediary network device using Linux kernel networking tools (e.g., `ebtables`, `iptables`/`nftables`, `pppd`, and bridge-utils) to terminate the PPPoE session and pass the public IP via proxy ARP/DHCP spoofing (IP half-bridge) directly to the downstream gateway without double NAT. It requires deep knowledge of ISP PPP negotiation, L2/L3 frame handling, MTU/MSS clamping, and kernel-space versus user-space packet performance. Vibe coding cannot navigate the intricate kernel-level routing and hardware compatibility issues inherent in low-level networking.
Discussion
20 comments analyzed.
Competitors mentioned: Unifi Cloud Gateway Fiber, AT&T fiber equipment, UDM Pro Max
Concerns raised: Buggy ARP implementation requires static ARP entries, PPPoE has high overhead and is overengineered, Expensive for carriers to implement properly, High latency with VLAN tagging enabled on ONT, Unsupported on cheap CPE devices
Feature requests: Support for IPoE with VLAN tagging as alternative to PPPoE, Better documentation of ARP behavior and issues
