01

Service overview

Firewall ACT is ACT Tecnologia's entry-point perimeter solution, built on a hardened Linux/BSD operating system in a compact, silent appliance. It delivers stateful firewalling, advanced routing, VPN, and network segmentation at a reduced cost and power draw, suited for branches, offices, and network points that need secure connectivity without the complexity of an enterprise appliance. All configuration, monitoring, and response is handled by ACT's NOC.

Secure perimeter

Stateful firewall with zone-based policies, NAT, controlled port forwarding, and blocking by source, destination, and service.

Advanced routing

Static and dynamic routing (BGP, OSPF), 802.1Q VLANs, multiple WAN links, and load balancing.

VPN connectivity

Site-to-site tunnels and remote access via IPsec, OpenVPN, and WireGuard, with hub-and-spoke topology for access to networks behind CGNAT, provided the hub has a fixed IP.

02

Network and routing features

Layer 3 / Layer 4: routing and segmentation foundation to connect branches, isolate environments, and prioritize critical traffic. All features below are configured and versioned by ACT.

Feature Status Description
Stateful firewall Included Session control by zone, source, destination, port, and protocol
NAT / Port forwarding Included SNAT, DNAT, and port mapping with audited rules
802.1Q VLANs Included Network segmentation by department, environment, or trust level
Dynamic routing Included BGP and OSPF for multi-site topologies
Multiple WAN links Included Failover and load balancing across carriers, with configurable weights
QoS / Traffic shaping Included Policy-based VoIP and critical traffic prioritization
DHCP and DNS forwarding Included Address distribution and resolution with local cache

Available features depend on appliance sizing and traffic profile.

03

Scope of coverage (layer 3/4)

Firewall ACT is a stateful network firewall (layers 3 and 4). Deep application inspection (layer 7) is covered by the FortiGate line. The table below makes the scope explicit.

Capability Layer Firewall ACT
Stateful firewall (by port/protocol) L3 / L4 ✓ Covered
NAT, port forwarding, and routing L3 / L4 ✓ Covered
VLAN, VPN, QoS, and multi-WAN L3 / L4 ✓ Covered
IPS (intrusion prevention) L7 ✗ Not covered
Application control (App Control) L7 ✗ Not covered
Web filtering / content filtering by category L7 ✗ Not covered
Web proxy with caching L7 ✗ Not covered
Antivirus / anti-malware at the edge L7 ✗ Not covered
SSL/TLS inspection L7 ✗ Not covered
Anti-bot / C&C detection L7 ✗ Not covered
High availability in a redundant pair N/A ✗ Not covered

For application inspection (layer 7) and high availability, FortiGate is the recommended solution. ACT sizes the right tier for each operation's needs.

04

VPN and remote access

Encrypted connectivity between sites and for remote users, supporting the three main tunnel technologies. ACT operates a hub-and-spoke topology to reach equipment behind CGNAT, which requires a fixed IP at the hub.

Technology Typical use Characteristic
IPsec Site-to-site Tunnels interoperable with other vendors, market standard
OpenVPN Remote access Flexible, over TLS, traverses NAT and restrictive environments
WireGuard High performance Modern tunnel, low latency, and lower CPU overhead

Technology choice depends on the client scenario and required interoperability. Tunnels provisioned and monitored by ACT.

05

Security and access control

Perimeter defense: Firewall ACT's protection combines edge traffic control, OS hardening, and administrative access governance, with logging and evidence for every change.

Traffic control

  • Firewall policies by zone and interface
  • Geo-blocking and IP reputation list blocking
  • Egress filtering to contain unauthorized traffic
  • Protection against scanning and flooding at the edge
  • Versioned rules with change history

Administrative access

  • Hardened operating system, reduced attack surface
  • Management access restricted to ACT's VPN
  • Key-based and individual credential authentication
  • Logging of administrative sessions
  • Security updates tracked by ACT
06

Management, monitoring, and automation

Centralized administration by ACT's NOC, with continuous Zabbix-based monitoring, proactive alerts, and versioned configuration; the client sees the health of the perimeter without operating the equipment.

Continuous monitoring

  • Metric collection via Zabbix (CPU, memory, links, tunnels)
  • Proactive alerts for link down and VPN failure
  • Availability and bandwidth usage dashboards
  • History for capacity and trend analysis

Managed operation

  • Configuration as code, versioned and auditable
  • Configuration backup before every change
  • Fast restore in case of hardware failure
  • Changes made in an agreed maintenance window
07

Specifications

Form factor Compact, fanless appliance for desktop or shallow rack
Power consumption Typically low power draw (reference below 15 W)
Interfaces Multiple Gigabit Ethernet ports for WAN, LAN, and DMZ
Operating system Hardened Linux/BSD system, maintained and updated by ACT
