VyOS Networks Blog

Hello, community!

We're back with an end-of-summer update. We've been quite busy cleaning up legacy code, fixing bugs, and adding remaining features planned for the future 1.4.0 (Sagitta) LTS release that we hope to finish by 2024. Soon, we'll create a sagitta branch in our git repositories to stabilize the codebase that will become the new 1.4.0 LTS release. Rolling release development will continue in the current branch, and the future 1.5 LTS release will be "Circinus". Meanwhile, the minor release 1.3.4 of the Equuleus branch is in its final stages, and we'll soon build and release its images. Here's what's happened in August.

VyOS 1.3 Equuleus

• VyOS 1.3 now supports virtual Ethernet pairs (T4825). They will connect network namespaces together when full support for netns is added.
• Removing GRE tunnel key works as expected again (T5223).
• IPv6 link-local addresses are now added to container interfaces (T5506).
• Support for running scripts on PPPoE session setup, teardown, and RADIUS attribute change (T3546).
• Fixes for low-impact security vulnerabilities, including the speculative execution issue in AMD CPUs.

We'll provide detailed release notes when 1.3.4 images are out, so stay tuned for updates!

• Support for static MACsec keys with peers (T5447):

  set interfaces macsec <interface> address <address>
  set interfaces macsec <interface> security encrypt
  set interfaces macsec <interface> cipher [gcm-aes-128|gcm-aes-256]
  set interfaces macsec <interface> security static key <key>
  set interfaces macsec <interface> security static peer <peer> key <key>
  set interfaces macsec <interface> security static peer <peer> mac <address>

• Ability to accept or deny wireless traffic based on MAC addresses (T5491):

  set interfaces wireless <interface> security station-address mode [accept|deny]
  set interfaces wireless <interface> security station-address accept mac <address>
  set interfaces wireless <interface> security station-address deny mac <address>

• DNS update timeout can now be manually set (T5445):

  set service dns dynamic timeout <seconds>

• Ability to manually wipe the dynamic DNS cache (T2546):

  clear dns dynamic cache

• Support for L3VPN label allocation mode (T5466):

  set container name <container> port <name> listen-address <address-1>

• The port field is now optional when configuring destination NAT redirection. Omitting it will default to the original port (T5472):
