A software Broadband Network Gateway, written in Rust, that runs on standard Linux servers — bringing carrier-grade subscriber management to small and mid-size ISPs. Handles PPPoE/DHCP termination, dynamic VLANs, per-subscriber traffic shaping, CGNAT and RADIUS AAA without the enterprise price tag.

AthenaBNG is a software-based Broadband Network Gateway that runs on standard Linux servers — carrier-grade subscriber management without carrier-grade hardware pricing.

Key features

Dynamic VLAN demux — automatic VLAN interface creation for 802.1Q, 802.1ad (QinQ) and nested configurations
PPPoE termination via accel-ppp with RADIUS authentication and per-session QoS
DHCP/IPoE with RADIUS-driven IP assignment and accounting
Per-subscriber QoS using CAKE traffic shaping with overhead compensation
CGNAT & VRF steering — VRF-based traffic routing to NAT appliances, deterministic CGNAT on the roadmap
Dynamic routing through FRRouting: BGP, OSPF, IS-IS
Full RADIUS AAA including CoA/Disconnect
A proper network OS CLI — JunOS/VyOS-style with tab completion, config mode, commit and rollback

Under the hood

Built in Rust on Linux 6.x, running on commodity x86 with modern NIC offloads. 10Gbps+ throughput with thousands of concurrent subscribers per server, and no vendor lock-in.

Who it's for

Small-to-medium Australian ISPs who need real subscriber management — backed by a Brisbane-based team that knows the NBN and the local regulatory landscape.
