TrustPort Net Gateway: Complete Installation and Setup GuideTrustPort Net Gateway is a network-level security solution designed to protect a business network by scanning and filtering traffic, blocking malware, phishing, and unwanted content before it reaches endpoints. This guide walks through planning, installation, configuration, and post-installation best practices for TrustPort Net Gateway, with practical steps and examples to help system administrators deploy and maintain the appliance effectively.
Before you begin — planning and prerequisites
- System requirements: Verify hardware or virtual machine resources meet TrustPort Net Gateway recommendations (CPU, RAM, disk). For production deployments, use a dedicated appliance or sized VM with at least the vendor-recommended CPU cores and 8–16 GB RAM depending on throughput needs.
- Network design: Decide deployment mode — inline (transparent bridge) or gateway (router/proxy). Inline is simpler for minimal network changes; gateway mode provides explicit routing and more granular control.
- IP addressing and routing: Allocate IP addresses for management interface, internal LAN, and upstream Internet (if in gateway mode). Ensure routes and firewall rules permit necessary management and update traffic.
- DNS and time: Ensure reliable DNS resolution and NTP for appliance time synchronization (important for certificate validation and logs).
- Licensing and updates: Obtain active TrustPort licenses and download the latest installation images and update packages from the vendor portal.
- Backups and rollback plan: Snapshot VMs or plan for appliance configuration backup before major changes.
Installation options
TrustPort Net Gateway can be deployed as a physical appliance, as a virtual machine (VMware, Hyper‑V, KVM), or as a cloud-based instance where supported. Choose the image and format that matches your environment.
- Download the appropriate installation ISO or VM image from TrustPort.
- Create a VM with recommended CPU, RAM, and disk. Attach the ISO to the VM console (for ISO) or import the provided VM image.
- Boot and follow the installer prompts (language, keyboard, target disk).
- Set a strong administrator password and note default ports for web console access (typically HTTPS on port 443 or a vendor-specified management port).
- After OS-level installation completes, the TrustPort Net Gateway web interface will be reachable at the appliance management IP.
Initial web console setup
- Connect a workstation to the same network as the appliance management interface.
- Open a browser and navigate to the appliance IP using HTTPS. Accept any self-signed certificate for initial setup (replace with a trusted certificate later).
- Log in with the admin credentials set during installation.
- Complete the guided setup wizard (if presented): set hostname, timezone, NTP server, DNS servers, and licensing key.
- Register the appliance with TrustPort updates/activation servers to enable antivirus and URL filtering updates.
Network configuration — inline vs gateway
- Inline (transparent bridge):
- Place the appliance between the edge firewall/router and the internal switch.
- No IP routing changes required for clients; appliance inspects traffic transparently.
- Configure bridge interfaces (WAN-facing and LAN-facing) and enable transparent mode.
- Gateway (router/proxy):
- Configure the appliance with distinct WAN and LAN IPs.
- Update default gateway on clients (or NAT/firewall rules) to route traffic through the appliance.
- Configure NAT or routing as required, and set DNS/HTTP proxies if using explicit proxy mode.
Example: configuring two interfaces for gateway mode
- eth0 (WAN): 203.0.113.⁄29, gateway 203.0.113.1
- eth1 (LAN): 192.168.1.⁄24
- Set appliance as default gateway for LAN clients or configure firewall rules to force traffic through the appliance.
Enabling core protection modules
TrustPort Net Gateway typically includes several modules — web filtering (URL categorization), antivirus/antimalware scanning, anti-phishing, SSL/TLS inspection, application control, and intrusion prevention. Enable and tune modules as follows:
- Antivirus scanning:
- Enable real-time scanning of HTTP, HTTPS, FTP and SMTP traffic.
- Configure file size limits and file type rules for scanning to balance security and performance.
- URL filtering:
- Import or subscribe to URL categorization lists from TrustPort.
- Create policies to block categories (e.g., malware, phishing, illegal content) and allow categories needed for business.
- SSL/TLS inspection:
- Generate or import a TLS inspection certificate; distribute the CA certificate to domain-joined clients or corporate mobile device management (MDM) platforms.
- Configure which hosts or categories to exclude from inspection (banking, healthcare portals, or high-sensitivity services).
- Anti-phishing and reputation:
- Enable reputation-based blocking and real-time updates.
- Application control:
- Define rules for blocking or throttling non-business applications (torrent clients, streaming where necessary).
- Email protection:
- If handling SMTP, configure scanning of inbound/outbound messages and attachment policies.
SSL/TLS inspection details
- Create a private CA certificate on the appliance and export the CA certificate for distribution.
- Install this CA into your Active Directory Group Policy (Trusted Root CAs) or MDM for managed devices so clients trust the appliance when it issues per-site certificates.
- Whitelist sensitive domains to bypass inspection (e.g., banking, payment providers, some cloud services) where intercepting traffic violates terms or causes issues.
- Monitor decrypted traffic and ensure compliance with privacy policies and regulations; avoid decrypting traffic for personal devices if policy prohibits it.
Policy configuration and user/group mapping
- Integrate with Active Directory/LDAP to apply user- or group-based policies. This allows granular rules like “Marketing group — allow social media; Sales group — allow LinkedIn only.”
- Create policy objects: time-of-day rules, bandwidth limits, content rules.
- Use policy hierarchy: global defaults, group-specific overrides, and per-host exceptions.
Example policy order:
- Block high-risk categories (malware, phishing) — highest priority.
- Business-allowed categories with logging only.
- Exceptions for admin systems.
Performance tuning and capacity planning
- Monitor CPU, memory, and I/O on the appliance. Heavy SSL inspection and archive scanning increase CPU usage significantly.
- Tune scanning: exclude large media file types from deep scanning, enable heuristics only where needed, set maximum file sizes for full scan.
- For high throughput, use hardware appliances sized for expected concurrent connections, or scale horizontally with multiple appliances and a load balancer.
- Enable caching for frequently accessed content and tune connection timeouts to reduce resource usage.
Logging, monitoring, and alerts
- Configure log retention policies and offload logs to a centralized syslog server or SIEM for long-term storage and correlation.
- Enable real-time alerts for critical events (malware outbreaks, failed updates, license expiry).
- Use dashboard widgets for top-threats, top-blocked URLs, and bandwidth usage.
- Periodically review logs for false positives and tune rules accordingly.
Updates and maintenance
- Keep virus definitions and URL categorization lists up to date. Schedule automatic updates and confirm update status daily.
- Apply firmware and software updates per vendor release notes; test updates in a lab before production where possible.
- Backup configuration regularly and before applying updates. Verify restore procedures by performing test restores on a spare appliance or VM snapshot.
Troubleshooting common issues
- Management console unreachable:
- Check network connectivity, firewall rules, and whether management service is running on the appliance.
- If locked out, use local console access to reset networking or admin password per vendor instructions.
- HTTPS sites failing after enabling SSL inspection:
- Ensure appliance CA is installed on clients and that pinned or certificate‑pinned sites are whitelisted.
- Check TLS protocol versions and cipher suites compatibility.
- Performance degradation:
- Inspect CPU/memory spikes, check for excessive scanning of large files, increase hardware resources or tune scanning rules.
- False positives blocking legitimate sites:
- Use URL allowlist and create exceptions for affected domains; submit samples to TrustPort for category correction.
