Malicious traffic stops before it reaches your server.
Fexwall is our DPDK-powered L3/L4 security layer. It blocks traffic with forged source addresses at the network edge, applies project-specific filters at high speed, and forwards clean traffic to your service.

Protection against forged source addresses
End-to-end protection
Every packet passes through the right layer before reaching your service
Traffic first passes through volumetric attack pre-filtering on the DPDK router. Fexwall then evaluates the remaining traffic against project rules, forwarding verified packets to your server.
01
Multiple traffic sources
Traffic from upstream, direct peers, and international connections.
02
DPDK edge router
Runs full-route and state tracking on TNSR, applying the first filter against Reflection and AMP-based TCP/UDP volumetric attacks.
03
Fexwall
DPDK-powered high-performance L3/L4 filtering, intelligent traffic analysis, and project-specific security profiles.
04
Protected service
Only verified clean traffic reaches your VDS or dedicated server.
Technology built in-house
More than a general-purpose firewall
Fexwall runs inside the Datafex network topology as an integrated security layer shaped around real service requirements.
DPDK-powered processing
Packets are processed on a performance-focused data plane so protection does not become an infrastructure bottleneck.
Source address validation
Traffic carrying forged source addresses is blocked at the network edge before it can reach the protected service.
Project-specific filters
Protection profiles are tailored to the traffic patterns of games, applications, and specialized workloads.
Stateful control
Connection flow is tracked to distinguish expected traffic from anomalous traffic more accurately.
Flexible access rules
Reduce your service surface with allow or deny rules based on protocol, source, and port.
Traffic visibility
Monitor bandwidth, packet flow, dropped traffic, and active rules from the customer panel.
