Important note when using the Weidmüller u-link Remote Access Service:

1. The u-link Remote Access Service is supported by firmware since version 3.0.2 Build number 72728 or later. If

a Router shall be used for u-link additionally to an existing configuration, please upgrade the firmware to the

latest available version without a factory reset (by disabling the checkbox “Set factory defaults of the new

firmware”).

2. If you will use any 6-Port Router model with u-link you need at least to update to version 3.2.1 Build 79368 or

later.

3. The u-link Remote Access Service can be used with each Weidmüller router model except the variant

IE-SR-GT-LAN-FN which does not support any VPN functions.

General Upgrade/Downgrade information:

Upgrade to version 4.x is only possible from version 3.5.0 or higher. For Routers with versions < 3.5.0 first update

to version 3.5.x followed by a final update to latest version.

Version 4.0.4, Build number 114187

Release date: January 04, 2020

Feature updates:

• The Syslog can now be stored on an inserted USB stick which has to be preformatted with a Linux ext4

filesystem. This feature can be enabled on the Event Log → Configuration page. The syslog files are

used as ring buffer. The file size depends on the size of the stick.

• IPsec IKEv2 can now be activated. By default, active connections are now initiated using IKEv2 but

IKEv1 connections are passively accepted.

• The Forwarding feature has been extended to forward UDP or TCP port ranges.

• Subnet mask value /0 is now allowed for u-link’s destination SNAT configuration parameter.

Bug Fixes:

• USB Sticks with FAT file system got formatted with the Linux ext4 file system when inserted. Bug was

introduced with version 4.0.1.

• USB sticks with configuration or firmware files have been processed correctly but the device was caught

in a reboot loop until the stick was removed. This regression bug was introduced in version 4.0.1 and

has been fixed now.

• Fixed a regression bug introduced with 4.0.1. NATing and filtering of active FTP was broken.

• 3G models did not get a DNS-Server from the mobile radio provider. This bug was introduced with

version 4.0.1.
