StartOS StartWRT 1.1.0

Original release notes

StartWRT 1.1.0 lets devices open their own port forwards, identifies devices that never tell you their name, and provisions eMMC boot firmware so a DIY board boots without its microSD card.

Highlights

  • Devices can open and renew their own port forwards using the standard PCP and UPnP protocols - a StartOS server configures itself behind the router, and game consoles and torrent clients are covered too. It is off by default: enable it per device with "Allow automatic port forwarding" on that device's page. A device can only ever forward ports to itself, manual rules always win, and ports the router itself answers on are refused.
  • Several devices can share one external port by hostname. A device can claim a name on a shared port such as 443, and the router delivers each TLS connection to whichever device owns the name it asks for - so several services, on one server or many, can live behind a single port. Remote access to the router's own interface keeps working alongside it.
  • Devices that never share a hostname are named by operating system or vendor - Windows device (3af2b1) or Apple device (3af2b1) in place of an opaque device-3af2b1. A real hostname still takes over when one appears, and names you assign always win.
  • A DIY BananaPi BPI-F3 now boots from eMMC. The flash wizard, in-app updates and a check on every boot write the release's own eMMC boot firmware, self-healing a board whose factory left it empty or carrying an incompatible bootloader.
  • MT7915-based Wi-Fi modules now work on DIY builds - the image ships their firmware alongside the MT7916 firmware.
  • The interface notices a newer firmware and catches up. An update installed from the current tab reloads the page once the router is back; one applied elsewhere offers a Reload button rather than reloading over unsaved work.
  • Publishing a port the router itself answers on asks for confirmation rather than silently cutting off remote access, SSH or an inbound VPN.
  • Disabled VPNs are no longer offered as a profile's route or as a chain target - picking one used to send that traffic straight out your Internet connection while every screen reported success.
  • The StartWRT user guide is published at docs.start9.com/start-wrt, including a Hardware page with the router's specifications and reference schematic.

Important

The IPv6 "Reserve" option is gone. Devices choose their own IPv6 addresses, so a router cannot reserve one - the toggle never worked. A device's IPv6 address is now shown read-only, and a published-port rule follows the device's current address on its own.

The Start9 DDNS provider option is gone until that service launches. A Dynamic DNS configuration saved with it now reads back as disabled; pick one of the supported providers to re-enable it.
