IX67 Firmware
The firmware in the Intertex SurfinBird IX67 can be upgraded to new versions as Intertex releases them. New firmware often include bug fixes and new features. Some Internet Gate models require special versions of the firmware. We recommend that you go to the login page of the Internet Gate web user interface and click "Check for newer" - that link automatically selects the suitable firmware for your model.

Release notes:

Additional SIP security functions in 5.10F10 firmware:

Protection against common SipVicious attacks, general DoS SIP attacks and SIP brute force password guessing has been added.

  • On the SIP Switch page, header information to protect against common SipVicious attacks is added in the Incoming Call Blacklist table when upgrading to 5.10F10.
  • On the Security pages, under General settings, SIP flood detection is added. The default values: Trigger levels: Low 5, High 40, Quarantine time 300 seconds are added when upgrading to 5.10F10.

  • SIP authentication setting added to static domain forwarding table. (To ease setting up extra authentication for remote users using a SIP PBX on the LAN.)
The addition of these security functions has been sponsored by Omnitor AB.
