• Syslog server support on remote OpenVPN links did not work properly.

Version 2.6.3, Build number 68963 Release date:

• Problem to manually reboot with selection of the second firmware image was fixed.

Version 2.6.3, Build number 68843 Release date:

January 26, 2015

Bug Fixes:

• IP-Forwarding from WAN to LAN interface sometimes did not work properly. This failure behaviour was

introduced in Version 2.6.3 / Build number 68653.

• DynDNS service could not be configured outgoing to LAN interface (No problem when configuring

DynDNS for WAN interface). This failure behaviour was introduced in Version 2.6.3 / Build number

68653.

Version 2.6.3, Build number 68653 Release date:

December 08, 2014

New features:

• Implementation of a fall back mechanism when the Firmware is updated. Even if the power supply fails

while updating process (Phase Flashing) is running an abort never will result in a broken device.

• Implementation of a “reboot timer” in menu System→Reboot. This feature is quite useful to remotely

test new configurations which might lead to a connectivity loss (e.g. based on an unintended firewall

configuration). If the reboot timer is activated the device automatically will reboot after the configured

time and will come back with the last saved configuration. The reboot timer can be deactivated in menu

System→Reboot (Cancel Reboot)

• The Router configuration (Backup file of type *.cf2) now can be loaded also by using an USB stick. The

cf2-file has to be placed on a USB Stick in the directory “settings” or “settings/<serial number>”. The

stick has to be inserted and the device has to be rebooted. The device will load the settings at boot time.

Bug Fixes:

• Patched OpenVPN DoS Bug CVE-2014-810. This update is recommended for all setups running the

Router as OpenVPN server with untrusted clients.

• Filter wizard Java Script error was fixed on insertion of predefined rule sets. Was broken since 2.6.0

Version 2.6.0, Build number 67659 Release date:

July 07, 2014

New features:

• Automatic fallback mode to a 3G connection if a remote target device no longer is accessible via the

WAN port. It is now possible to actively monitor a target IP address via ICMP over the Ethernet link. In

case of failures the 3G uplink will be activated.

• 3G interface now can be used for static device routes

Bug Fixes:

• OpenSSL Update to version 0.9.8za (CVS-2014-0224). Update is recommend for all OpenVPN users

with an IE-SR-2GT-xxx OpenVPN counterpart at least on one side of two devices. Otherwise the

connection is vulnerable to a Man-in-the-Middle attack due to a OpenSSL bug if both sides of a VPN

connection have a vulnerable version of the OpenSSL library

Version 2.5.1, Build number 67460 Release date:

June 02, 2014

Bug Fixes:

• German Umlauts were broken on the Permissions page since version 2.3.2

• NTP time synchronization and NTP server relay features have undergone a big cleanup. This includes a

new NTP server state page in the web interface. Update is recommended for everyone using the NTP

server relay or a highly accurate time synchronization.
