Change Log firmware Security Router IE-SR-2/6GT-series

• 1:1 NAT now allows an overlapping of local network IP addresses and 1:1 NAT mapping address

spaces. Previously the web interface blocked this configuration.

Version 2.3.3, Build number 66690 Release date:

January 24, 2014

New features:

• Firmware adapted to be used also for new model IE-SR-2GT-LAN-FN, means that this firmware version

can be used for all Weidmüller Router models

o IE-SR-2GT-LAN →LAN/WAN Router. General features: Routing, Firewall, NAT, VPN IPsec

and OpenVPN

o IE-SR-2GT-LAN-FN →LAN/WAN Router. General features: Routing, Firewall, NAT, No VPN

o IE-SR-2GT-UMTS/3G →LAN/WAN Router plus additional 3G interface. General features:

Routing, Firewall, NAT, VPN IPsec and OpenVPN

• The integrated HTTPS web server now is using a unique self signed certificate generated on factory

defaults.

• Performance improvements for pure layer 2 filter without connection tracking.

• 1:1 NAT did not work as uplink network mapping or on local networks with communication across

attached IP routers

Bug Fixes:

• Web access restrictions to the HTTP(S) server on the 3G interface did not have an effect.

• 3G connections on private APNs without DNS servers were not marked as CONNECTED because the

DNS server was missing.

Version 2.3.2, Build number 65829 Release date:

September 20, 2013

Bug Fixes:

• The Forwarding table (Port- and IP-Forwarding) had a wrong sorting for more than 10 entries.

• Under special conditions the DNS server of the 3G interface was used even if the corresponding

checkbox was disabled.

Version 2.3.2, Build number 65490 Release date:

August 02, 2013

Bug Fixes:

• Problem to show the Forwarding table correctly in Web interface page was solved (caused by a Java

script error occured by using Microsoft Internet Explorer).

• A “Dial-On-Demand“ configured 3G/UMTS connection was unintentionally initiated each time a

configured NTP time server tried to do a time synchronization even if internal IP addresses are used for

NTP time server (cause by an unintended DNS lookup).

• The internal connection tracking table was increased to 32768 entries providing more robustness against

DoS attacks and high load.

New features:

• Forwarding table (IP and Port forwardings) now has a new column for comments

• IPsec connections now can be switched by using the VPN key input. Configured connection entries have

to be set to the mode “Active (Switched)”

Version 2.3.1, Build number 64408 Release date:

April 12, 2013

Bug Fixes:

• Web configuration: Removed the possibility to disable the HTTP server completely in menu ‘Web

server’. Use alternatively menu ‚Web access‘ to disable HTTP access.

• Web access control on the LAN port did not work. Access was allowed in any case.

• Function ‘Client monitoring’: Round trip time to control connected clients (if still alive) now can be set up

to 5000 ms as maximum. Old maximum round trip time of 1000 ms was very noisy on 3G links.

• Explicit setting of Ethernet transmission mode like 100 MBit/half duplex was not applied on reboot after

power down. Instead auto negotioation was used again.

New feature:

• Function ‘Client monitoring’: Allowing reset of the 3G modem if a client monitoring entry fails. This is very

helpful on special M2M APNs which might need a 3G network re-registration after some time.
