Built by an ISP · Runs Our Own Network

ST-vBNG Software
Broadband Gateway.

A software BNG / BRAS that terminates PPPoE & IPoE subscriber sessions on a standard server — RADIUS AAA, NAT & firewall, VLANs, connection logging and live monitoring, all from one web console. No dedicated hardware gateway required.

Software BNG / BRAS

A full broadband gateway,
in software.

Everything a hardware BRAS does — session termination, AAA, NAT, firewall, logging and monitoring — on a server you already know how to run.

PPPoE & IPoE Termination
Terminate PPPoE and IPoE subscriber sessions on your own server — the software BNG/BRAS that replaces a dedicated hardware box.

Live Session Monitoring
Watch every session live — per-subscriber download/upload, uptime, rate-limit, IPv4/IPv6, MAC. Search, sort, graph, torch, or drop a session.

FAQ

Software BNG, answered.

What is a software BNG?

A Broadband Network Gateway (BNG, also called a BRAS) terminates subscriber sessions — PPPoE and IPoE — authenticates them via RADIUS, assigns IPs and enforces rate limits. ST-vBNG does this in software on a standard server, so you get BNG functionality without buying a dedicated hardware gateway.

Does ST-vBNG replace a hardware BRAS?

For many ISP scales, yes. It runs on commodity x86 hardware (see the recommended builds) and terminates thousands of concurrent PPPoE/IPoE sessions with RADIUS AAA, NAT, firewall and logging — the core roles of a hardware BRAS.

Does it work with ISPRadius?

Yes. ST-vBNG is a separate product with its own RADIUS configuration, so it runs standalone — or you can point it at your ISPRadius RADIUS servers, which is the recommended setup at enterprise scale.

How are configuration changes applied safely?

Every change is edited in a form and applied with Save & reload. A timestamped snapshot is written automatically before each change, so any config can be restored — and NAT/firewall edits go live behind a commit-confirm window that rolls back if you lose access.

Is subscriber connection logging supported?

Yes. New connections are recorded (PPPoE username or IPoE MAC) to local files and can be forwarded to a remote syslog server, for compliance and troubleshooting.
