Version 11.0.21


A new Wake on LAN feature has been added. With this tool, system administrators can wake up dormant devices connected to the Secure LAN or DMZ. This feature allows you to reduce energy costs and extends the hardware lifetime by ensuring that resources are used efficiently.

AXS Guard Cloud Notifications

The AXS Guard cloud will automatically notify you when configuration changes are made to AXS Guard appliances that you manage. These notifications will let you know whether the changes were applied successfully or not, making it easier to keep track of configuration changes, troubleshoot and manage your AXS Guard appliances.

Reverse Proxy

The password auto-learn capabilities for RDG and RDP logins have been enhanced. Many organizations require users to change their passwords regularly, which creates challenges due to the need for immediate password updates. Users frequently opt for appending extensions to their current passwords for convenience.

This practice resulted in issues with the auto-learn function, as it recognized the old password as a match and considered only the added extension as a new password to learn. To address this, we've expanded the password auto-learn feature to recognize multiple passwords and iterate through them, in order to determine which one is eventually accepted by the backend system.

Firewall Logging

The firewall logs have been enhanced to include DHCP hostname information. Reading, remembering, and searching for IP addresses in extensive firewall logs can be challenging. As of now, if a source or destination IP address belongs to a local LAN with DHCP enabled, the log will show the hostnames associated with the active DHCP leases.

Other Improvements

  • Pass version and revision information to the AXS Guard cloud backup service.
  • Write VPN in uppercase in the security settings for OpenVPN service names.
  • Allow underscores in domain names when parsing messages from dnsmasq.
  • Fix the logout functionality for Reverse Proxy HTTP Session Management.
  • Implement IPv6 DNS response filtering to prevent DNS security from being bypassed.
Version 11.0.20

Simplified Firewall Configuration

  • Firewall rules can now be set using a single field for domain names and IP addresses. This makes it easier to create and manage firewall rules.
  • Existing FQDN rules will now apply to the main domain as well as its subdomains. This means that you can create a single rule to match traffic related to a domain and all of its subdomains.

Firewall Logging

We have enhanced our firewall logs to include the domain names associated with the IP addresses found in DNS responses. This makes it easier to identify traffic destinations that are being blocked by the firewall.

Reverse Proxy Login Page

A button has been added to the Reverse Proxy login page allowing users to reveal their password while typing it. This makes it easier to enter their password correctly.

Other Improvements

  • PAX now supports static DHCP leases within VLAN setups. This allows you to assign static IP addresses to devices within a VLAN.
  • Specific warnings related to port redirection have been removed to streamline the user experience.
  • An issue that prevented SecureDNS from resolving domain names when the time was incorrect during boot-up has been addressed.
  • When a certificate is close to expiring, a clickable link will appear on the system dashboard. Clicking the link takes you directly to the relevant certificate page, saving you time and effort.
Version 11.0.19

System Administration Dashboard Improvements

The AXS Guard System Administration Dashboard displays system health messages.

Multiple alerts that are related are now grouped together, and each alert has a link to the corresponding configuration page, making it easier for system administrators to investigate and resolve reported issues. Please note that alerts for configurations that have been disabled or are not in use will no longer appear on the system dashboard.

Personal AXS Guard

An option has been added to allow system administrators to choose which PAX clients should be monitored via the system administration dashboard. While all PAX units are monitored by default, administrators can choose to disable monitoring for specific units by navigating to the PAX client configuration page.

OpenVPN Connect Client 3.4

AXS Guard automatically generates OpenVPN configurations, enabling system administrators to swiftly deploy VPN access for users.

However, there is a bug in OpenVPN Connect Client version 3.4 that triggers an error when used with our OpenVPN configuration files. To rectify this issue, we have implemented modifications to ensure that the generated AXS Guard OpenVPN client configurations remain compatible with version 3.4 of the OpenVPN Connect Client.

Version 11.0.18

Port Forwarding & Port Redirection

The LAN interface is now available for both port forwarding and port redirection. This enhancement enables you to exclude VPN connections when creating rules, providing more flexibility and control over your network configurations.

PKI: Support for ECDSA Certificates

In addition to RSA certificates, you can now upload certificates that make use of elliptic curve cryptography (ECDSA) for deriving the public key and certificate signing keys. ECC offers the advantage of smaller key sizes compared to non-EC cryptography (such as RSA) while maintaining equivalent security levels. Therefore, ECDSA certificates are the preferred choice when higher efficiency is required.


  • Resolve a configuration conflict related to the default SMTP authentication port.
  • Prevent legitimate e-mails containing French accents (U+00E9) from being deleted.


  • Whitelist additional Windows update URLs.
  • Remove mandatory locking.

Other improvements and bug fixes

  • System: Load the coretemp kernel module at boot. This module permits reading the DTS (Digital Temperature Sensor) embedded inside Intel CPUs, which is required to monitor system temperatures with htop.
  • User Authentication: Enforce a RADIUS timeout ranging from 3 to 60 seconds, aligned with the specifications of FreeRADIUS.

DNS Filtering Feature

System administrators now have the flexibility to enhance the existing SecureDNS filters by incorporating additional ones as per their specific requirements.

These supplementary DNS filters are built upon web access filter categories, allowing administrators to exert greater control over the network's DNS resolution process.

Typical use cases include, but are not limited to, blocking domains related to gambling, NSFW content, phishing, malware and more.

Firewall Updates

A firewall rule was added to allow WhatsApp by default.

WhatsApp is widely used for communication purposes, both personal and professional, making it a convenient and familiar platform for users. By allowing WhatsApp, organizations can facilitate seamless communication among employees, clients, and partners, enhancing collaboration and productivity.

Firewall rules for Isabel 6 were added to the fwd-banking policy.

E-mail Authentication

A dedicated smtpd instance has been added to better support SMTP authentication.

Allowing SMTP authentication on another smtpd port provides enhanced security by enforcing stricter measures for authenticated email transmission, enables differentiated access control for authenticated users, and ensures compatibility with certain applications.


System administrators can now generate reports for traffic that has been blocked by the GeoIP filtering feature.

Other improvements and bug fixes

  • Tool: Update context-sensitive help & documentation for the Reverse Proxy request filtering option.
  • Application Control: Fix layer7 kernel modules.
  • E-mail: Mark e-mails sent by AXS Guard as local.
  • High Availability: Increase DRBD buffer sizes.
