XT-6605, XT-6606, XT-6632 VERSION 1.04 March 20, 2019

This release corrects the following issue:

- The bridge server, when running in TCP or Both mode, may unexpectedly terminate due to receiving an invalid network packet. The server would automatically recover, but would cause a 30 second network disruption.

- The bridge server, when running in TCP or Both mode and set for no encryption, may unexpectedly terminate when a remote TCP client disconnects.The server would automatically recover, but would cause a 30 second network disruption.

- Corrected several typos with serial setup.

----------

XT-3306 VERSION 1.03 March 20, 2019

This release corrects the following issue:

- The bridge server, when running in TCP or Both mode, may unexpectedly terminate due to receiving an invalid network packet. The server would automatically recover, but would cause a 30 second network disruption.

- The bridge server, when running in TCP or Both mode and set for no encryption, may unexpectedly terminate when a remote TCP client disconnects.The server would automatically recover, but would cause a 30 second network disruption.

XT-3306 VERSION 1.02 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.

XT-6605, XT-6606, XT-6632 Firmware V1.01 Release Notes 2/1/2017

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.

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.

This release adds the following feature:

A layer-3 firewall was added in front of the tunnel server untrusted port. Since the XT products allow 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 "Ethernet Tunnel - Server Firewall" page. This will reduce nuiance log entries.

XT-3306 Firmware V1.01 Release Notes 2/1/2017

This release corrects the following:

Instead of being set to the static MAC address assigned to the device, the system was generating a random virtual MAC address. This was corrected and LAN1 is now set to the assigned MAC.

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.
