Juniper MX Filtering Gateway — always-on DDoS protection at line rate

A ready-to-deploy Juniper MX204 (4×100GE) gateway that drops attack traffic in hardware at line rate, driven by WanGuard detection and BGP FlowSpec. Two products, one solution — delivered by ITORO.

What it is

Hardware line-rate filtering, always on

Cloud scrubbing reacts in tens of seconds and adds cost per Gbps. An on-prem Juniper MX gateway filters malicious traffic the moment WanGuard detects it — at the router, in hardware, without redirecting your traffic anywhere.

4×100GE

MX204 gateway throughput — sized for ISP and data-center edges.

<5s

WanGuard detection triggers FlowSpec rules onto the MX automatically.

Line rate

Attack traffic dropped in hardware — clean traffic passes untouched.

How it works

WanGuard detects, Juniper MX filters

WanGuard sees your traffic via a port mirror and identifies the attack in seconds. It then pushes granular BGP FlowSpec rules to the Juniper MX, which enforces them at line rate on the forwarding plane. RTBH remains available as a last-resort fallback for attacks too large to filter granularly.

See how WanGuard works ›

  • Always-on — no traffic redirection, no scrubbing-center latency.
  • FlowSpec on the MX line cards; RTBH as fallback.
  • Pre-configured filter package tuned by ITORO.
  • Pairs with Juniper MX Telemetry for full NOC visibility.
Two-layer defense

Juniper MX — always-on DDoS protection

A line-rate stateless firewall, active before any attack reaches your network: transit DDoS filtering on the WAN/LAN interfaces (Layer 1) plus routing-engine protection via lo0 CoPP (Layer 2).

⤢ Click to enlarge Juniper MX always-on DDoS protection: Internet through an input filter (uRPF anti-spoofing, anti-amplification), lo0 Routing Engine CoPP, and an output filter to your network — Layer 1 transit protection on WAN/LAN interfaces and Layer 2 routing-engine protection.
Filter package

Juniper MX filter package — depth & complexity

Delivered by ITORO as a ready-to-deploy configuration.

Filter scale

Transit filters — hard-blocked categories

  • Rate-limited (policed, not dropped): SYN floods · IP fragments · ICMP · DNS · NTP.

Routing Engine CoPP

  • Default-deny — all unmatched traffic blocked.
  • Thousands of potential attack vectors eliminated by architecture alone.
Visibility & anti-spoofing

Every filter term has a named counter

  • Real-time visibility via Grafana and Juniper Telemetry.
  • Counters follow structured naming — protocol, direction, attack type.
  • Live monitoring available also from the JunOS CLI at any time.

Anti-spoofing — uRPF on all interfaces

  • Validates source IP addresses before any filter processing occurs.
  • Feasible-path mode — supports asymmetric routing in multi-homed environments.
  • Dedicated fail-counter — RPF violations logged separately from DDoS counters.
Why the MX gateway

Predictable cost, full control

No per-Gbps fees

Own the hardware; no metered cloud-scrubbing bills that scale with attack size.

Your data stays yours

Traffic never leaves your network — important for ISPs, telecoms and regulated operators.

Deployed by a Gold Partner
