Allow configuration of interfaces on which DNS relay service is running (by default DNS relay service is
enabled on each network interface.

Bug Fixes:
Improvement of system stability by optimizing memory controller parameters.
Fix of denial of service vulnerability and Pre-authentication remote crash/information disclosure for
clients when using “http_proxy_passthrough” in OpenVPN (CVE-2017-7520).
Fix of dnsmasq function (CVE-2017-13704).
Fix of OpenSSL vulnerability by update to version 1.0.2l (CVE-2017-3736 and CVE-2017-3735).
Fix of unreliable detection when inserting a cellular SIM card.
Fix of memory leak which could lead to problems regarding a cellular-based (mobile) u-link VPN
connection.
Version 3.1.2, Build number 77018 Release date:
July 14, 2017
Feature update:
Adaption of behaviour when restoring a backup configuration via USB stick (using backup file of type
<name>.cf2).
New procedure:
1. Copy cf2-backup file to USB stick (FAT or FAT32) into directory named settings.
2. Plug USB stick into the Router and power-up / reboot the device (Router automatically will load
the cf2-file).
3. Wait around 1 minute until the Router is ready again (PWR LED is lit constantly), having loaded
the parameters of the configuration file.
4. Un-plug USB stick from Router.
How to check the result of the import procedure via USB stick:
1. Plug USB stick into a PC and check directory settings which now should have a new sub
directory with name same as the device serial number (e.g. AX1367406). This directory
contains a log file named settings.log created by the Router at configuration upload.
2. Open text file settings.log and check the status of the restoring process (e.g. containing
message “Device configuration successfully updated”).
Note:
If you will use the same USB stick - containing a general template configuration file - for an initial setup of several
Routers, then each Router will create during the restoring process its own sub directory AX.... (based on the
unique serial number) below directory settings containing in the sub directory the Router specific text file
settings.log.
Bug Fixes:
u-link: DNS related problems fixed in terms of WWH-function when DNS settings have been changed.
Counters for dropped/overrun packets of Ethernet Interfaces (LAN / WAN) now will be reset at system
boot.
Now short DNS names (<4 characters) to be used with DNS provider dyndns.org are allowed.
Bug fix in terms of static configured link parameters of Ethernet ports (no Auto-Negotiation). No change
of configured parameters after system boot (Elimination of fallback to 10Mbit/half after reboot when no
link is available).
Bug fix in terms of assignment of the default gateway via 3G. A setting could be get lost when opening IP
configuration page and applying the settings.
Several security updates.
Version 3.1.0, Build number 74521 Release date:
December 05, 2016
New features:
A saved configuration file (with extension .cf2) created from any Router model (IE-SR-2GT-LAN, IE-SR-
2GT-LAN-FN or IE-SR-2GT-UMTS/3G) now can be load into any other Router model. All relevant
parameters of the target Router will be imported. Not relevant parameters (eg. 3G configuration
parameters when importing a backup file from a 3G-Router to a LAN/WAN-Router) will be ignored.
Update of OpenSSL library to version 1.0.2j
Improved calculation of CPU Load
