FT-Family Firmware History (Including FT-Soft)


VERSION 3.02

September 19, 2017

This release corrects the following issue:

Ethernet Tunnel configuration changes cause a slow response from the web browser. This issue is not fatal, but is annoying. It is a result of implementing a new MAC address range for the Ethernet controllers and the way MAC addresses are prioritized in a bridge.

----------

FT-6601, FT-6602, FT-6630 firmware Version 2.08 1/27/2017

1.0 INTRODUCTION

This release add the following features:

A layer-3 firewall was added in front of the untrusted tunnel server port. Since the FT products use TCP for the tunnel connection, this opens up the problem of nuisance TCP connections to the server. The layer-3 firewall can be configured to match on source IP addresses and allow or block the connection. The new feature is found on the "Tunnel - Server Firewall" page.

- This modification only applies to the FT-6602. A method of setting the unit to defaults, without a serial terminal was implemented. After applying power, the unit will illuminate all three LEDs on the front of the unit. When all three LEDs turn off, the user must press and hold the reset button. Once the user sees LED 2 blink on then off, the button may be released. The unit will now be running with default settings. The user must then reconfigure the device without removing power. Otherwise the unit will return to the previous configuration.

The system will now attempt a reboot in the event of a system error.

This release corrects the following:

There was a race condition in the tunnel fail-over feature that could result in a client simultaneously connecting to both the primary and alternate server. Any unit configured with fail-over backup connetions should install this update. This issue was corrected in V2.31, but is being repeated in this notice.

If DHCP is enabled and a DHCP lease is lost, the device would receive a new address, but the DNS requests would continue to be sent using the defunct IP address. This would result in never receiving a DNS reply and failure to resolve a name. This type of failure is likely to occur only when a router, also acting as a DHCP server, goes down for a period of time longer than the DHCP lease.

FT-Soft V1.03 Release Notes 10/20/2015

This release modifies FTSoft for Windows 10.

Please note: If a user attempted to install an older FTSoft package on Windows 10, Windows 10 will have erased the Software Key. They then have two options. 1) Completely uninstall FTSoft and then reinstall with this new package. 2) Install this FTSoft package on top of the old installation. Then go into the "DCB Virtual Ethernet Adapter Properties - Advanced Tab" and manually set the Software Key. Method 2 will preserve their old configuration and security certificate.

FT-6601/02/30 firmware Version 2.07 2/2/2015

1.0 INTRODUCTION

This release add the following features:

Support for remote syslog.

----------

FT-6601, FT-6602, FT-6630 firmware Version 2.06 2/2/2015

1.0 INTRODUCTION

This release add the following features:

- The OpenSSL FIPS encryption module was updated to version v2.0.8 (certificate #1747). OpenSSL was updated to v1.0.1j. These updates allow the FT to support certificates signed with SHA256.

- A new option was added to "Generate CA Key". The user may select between certificates signed with SHA1 or SHA256. This is provided for backward compatibility. Going forward, customers should select SHA256 when setting up a new system. However, if the customer has units running firmware v2.05 or older, they will need to keep using SHA1 certificates. Note: FT-Soft already supports SHA256.

- The FT's web server was configured to refuse SSLv3 connections. SSLv3 is considered broken and should no longer be used.

- The default web server certificate has been updated to SHA256 signature with 2048-bit RSA. Note: This will cause interoperability problems with systems running Windows XP SP2 and older.

- When generating web server/browser certificates, the new certificates will also be SHA256 signatures with 2048-bit RSA.

NOTE: The OpenSSL FIPS v2.0.8 encryption module has more overhead than the older v1.1.2 module we were previously using. This overhead has resulted in a 33% reduction in performance.

This release correct the following:

- v2.05 added support for NTP and timezones, but this introduced a problem with manually setting the time. On boot, the FT reads the time from the RTC and interprets it as UTC. However, when the clock is manually set, it was stored to the RTC in the local time for the timezone. This would cause the time to be wrong the next time the system rebooted.

----------

FT-6601/02/30 firmware Version 2.05 6/19/2014

This release add the following feature: - Network-time protocol (NTP) client support was added. A glitch in the RTC or a dead RTC battery is fatal for the FT products since certificate verification relies on having the correct date and time. This addition helps prevent that condition.

----------

FT-6601/02/30 firmware Version 2.04 1/10/2014

Repaired a UDP Transport mode race condition. When the connection transitions from TCP to UDP where the server may lock-up.

----------

FT-6601/02/30 firmware Version 2.03 9/25/2013

- Added Alias functionality on LAN 2 interface
- Manufacturing version revision.

----------

FT-Soft Software FT Client Version 1.0 5/24/2010 1.0 INTRODUCTION This is the initial release of the FTSoft Windows client.

----------

FT-6601/02/30 firmware Version 2.02 1/24/2011<

Manufacturing version revision. No functional changes.

----------

FT-6601/02/30 firmware Version 2.01 4/27/2010

This release corrects the following:

- The "Addl. Clients" menu item was not displayed when the Tunnel Mode was set to both.

This release adds the following feature to the FT-6601/02/30 firmware:

- The number of simultaneous clients was increased from 4 to 12. The first one is configured on the tunnel configuration page. The additional 11 are configured on the "Addl. Clients" page.

----------

This release V 2.0 adds the following features to the FT-6601/02/30 firmware 3/18/2010: 1.0 INTRODUCTION

- Added UDP Transport support. UDP mode is enabled from the Tunnel-Advanced page. An FT server is now capable of supporting a mix of TCP and UDP clients.

- switched from a blocking to a non blocking name resolver in the bridging code. This is better suited for clients configured to fail-over to a backup server.

- Modified the bridge to automatically switch to 802.1q mode if 802.1q tagged frames are detected.

- Added IGMP snooping feature.

----------


This is the initial release of the FT-6630 firmware.

This is the firmware revision log for the FT family bridges.

FT-6601, FT-6602 VERSION 1.03 10/30/2009

1.0 INTRODUCTION

This release corrects the following in the FT-6601/FT-6602 firmware:

- The bridge server was incorrectly limited to 8 client connections. The limit was raised to 25.

- Local key and Web certificate changes were not being activated requiring the unit to be reset before they would take effect.

1.0 INTRODUCTION This is the initial release of the FTSoft Windows client.

FT-6601 FT-6602 VERSION 1.02 12/05/2008

1.0 INTRODUCTION

Corrected a problem in the bridging software would cause a write_retry failure in the SSL library resulting the the SSL connection being aborted. This manifests whenever there is a backlog of data on the untrusted link.

Corrected a problem in the bridging software could result in a deadlock on the SSL connection. This manifests whenever there is a backlog of bi-directional data on the untrusted link.
