Latest maintenance release adds syslog TLS, AWS Gateway Load Balancer tunnel handler support, expanded BGP policy controls, and over fifty bug fixes.

POWAY, Calif., Dec. 17, 2025 – VyOS Networks today announced the availability of VyOS 1.4.4 LTS, the newest maintenance release of the VyOS Universal Networking Platform for bare metal, cloud, and edge environments.

VyOS 1.4.4 LTS strengthens secure operations, cloud deployment patterns, and routing policy control for organizations standardizing on an enterprise-grade open-source networking platform across hybrid infrastructures. The release delivers a consistent network operating system that runs on commercial off-the-shelf (COTS) hardware, major hypervisors, and public cloud providers including AWS, Microsoft Azure, and Google Cloud Platform.

Key highlights in VyOS 1.4.4 LTS include:

  • TLS support for syslog, enabling encrypted log transport for more secure observability workflows.
  • AWS Gateway Load Balancer tunnel handler support (AWS only), improving fit for GWLB-based traffic-steering and inspection architectures.
  • An option to match BGP prefix origin validation extended communities in route maps, enabling more granular policy decisions in RPKI-aware environments.
  • Over fifty bug fixes, improving stability across production deployments.

Important notes for upgrades:

  • Multicast addresses can no longer be manually assigned to interfaces. This may impact older malformed configurations and should be reviewed during upgrade planning.
  • SSH DSA keys are deprecated. Due to changes in OpenSSH, DSA keys will stop working in VyOS releases after 1.5. Users should migrate accounts to modern key algorithms ahead of time.

“VyOS 1.4.4 is a practical release focused on secure operations, cloud readiness, and policy control,” said Santiago Blanquet, Chief Revenue Officer at VyOS Networks. “It helps teams run a consistent network OS across environments while improving the security posture and reliability operators need in production.”
