Feature Releases

New features, e.g. hardware support for new modules or new products are first introduced in so-called feature releases. After successful field tests and if there is a general need for those new features they will become part of future mainline releases. Feature releases are based on a prior mainline release and have the third number in the version increased (e.g. 3.8.1 or 3.8.2).

You find all feature releases on our FTP server under “testing”.

Release History

New in Version 4.1

Feature First introduced
Limit band width per Wi-Fi client: In AP mode the maximum band-width may be limited per Wi-Fi client.
GUI improvements: On interfaces which show a minus symbol to remove entries (i.e. firewall rules) the corresponding setting was deleted immediately. This is now safeguarded by an alert to prevent accidental remove of settings.
Firmware blobs: To comply with RED is not possible to load unsigned firmware blobs any more. All firmware blobs are signed now.
Timezone update: The timezone list has been updated to version 2017c.
SNMPv3 engine ID con1guration: Engine ID for SNMPv3 traps can be configured now.

Performance Improvements: We have applied multiple performance enhancements to the system which range from software related improvements up to faster hardware access. They offer a smarter interrupt handling for high-speed transfers over USB-based LTE modems, faster memory access and less-consuming Ethernet packet dispatching. WLAN connections are now operating with a proper transmit power. We have also optimized the watchdog to cope with high system load. Newer versions of NB1600/NB2700 are also shipping with a faster CPU now.
NTP Server Extensions: We have upgraded chronyd to the latest version 2.29.1 which improves compatibility for clients and also fixes some security isses. The NTP server has received additional options to tune its synchronization behaviour. The poll interval, for instance, can be configured now. It is further possible to control access from a particular subnet and to trigger synchronisation manually.
DHCP Server Extensions: The DHCP server is now able to operate as relay agent and relay server. For IP/MAC bindings we have added support for pre-defined static hosts and an option to ignore undefined hosts. Further DHCP options (such as Agent-ID or WINS server) can be specified now.
GPS Daemon Upgrade: The GPS daemon has been upgraded to version 3.9 which is now able to deliver GNSS information in JSON and NMEA format. Clients are nowadays using the new JSON format (see the Berlios site for getting more details). Therefore, it represents the factory default mode now. All legacy modes are still available and backward-compatible to 2.37 clients, so that the new server will integrate flawlessly in existing environments.
IP Aliases: Ethernet-based interfaces are now supporting IP aliases and most applications (HTTP, SSH, Telnet, NTP, etc) can be addressed by those. However, the voice server does not work with IP aliases.
New Provider Database: We have incorporated Gnome’s mobile broadband provider information in order to offer accurate and up-to-date provider settings (APN, username, password) when setting up a WWAN connection.
Support for Sierra MC7700/MC7750: The QMI-based Sierra MC7700 and MC7750 modems are now supported.

They can be enabled by their vendor and product ID (wildcards are supported) and also be connected during runtime (hotplug). The range of available drivers provide support for pl2303- and ch341-based adapters (like the Prolific PL230 and ATEN UC232A) as well as pegasus-based Ethernet/RNDIS adapters. Please ask our support team whether your desired device is supported.
Improved Software Update: The new software update facility enables on-the-fly updates and requires almost no additional memory anymore.
New WLAN Features: We have added support for the WLE200NX module which allows 802.11a operation in the 5 GHz band. Please note that we do not support Dynamic Frequency Selection (DFS) at the moment, thus the range of channels is limited according to local regulations. Nevertheless, we have updated the registry database for operating with a proper transmit power in the available channels. We have also added support for 802.1x certificate-based authentication (WPA-EAP-TLS) and WEP when operating as client. The MTU of the WLAN interface can be configured now.
New SDK Functions: The virtual memory size of a script is now limited to 5MB and it can be monitored individually by the watchdog. The range of SDK API functions have been extended to:
  • Generating user-defined web pages
  • Listing, transferring or deleting files from an FTP or HTTP(s) server
  • Scanning available WWAN or WLAN networks
  • Various network-related functions (e.g. for sending ARP or WakeOnLAN packets)
  • Other system functions (e.g. sending SNMP traps)
IPsec Improvements: NAPT between IPsec peers (especially in case of holding the default route) works more reliably now. Broadcast packets are not encapsulated anymore. It is possible to configure the DPD action and force encapsulation. For roadwarrior configurations, the remote peer can be specified with
SNMP Agent Enhancements: We have added SHA/AES for authentication via SNMPv3. Administrative access via SNMPv1/v2c is now possible from a distinctive subnet.
OpenVPN Enhancements: OpenVPN has been upgraded to version 2.3.2 and it is now feasible to operate with dynamic hostnames. Server and transfer network as well as MTU can be configured.
Firewall / NAPT Enhancements: It is now possible to specify IPsec interfaces, they can also be applied as additional selector for the outgoing interface. Addresses can be grouped and those groups can be used instead of adding multiple rules. By using the LOCAL specifier, it is possible to select packets coming or going to local applications of the box.
IP-Passthrough: It is now possible to implement a pass-through of the WWAN IP address towards a LAN host (e.g. first DHCP client). More or less, the system acts like a modem in such case which can be helpful in case of firewall issues.
Temperature Indication: The system will now show the board temperature (available on NB3700) as well as temperature values derived from sensors of the modems.
CLI Enhancements: The CLI is now showing additional information (such as WWAN download/upload rates, IMSI, ICCID and SIM number) as well as details about the running configuration (name, version, hash). Scanning WWAN and WLAN networks is now possible and it can be used to get debug messages and to generate/send tech reports. We have also added a history command for showing the list of previously entered commands. Startup and config operations will be much faster now
Distintive Supervision: It is now possible to configure ping supervision on a per-link basis. A retry interval option has been added for reducing the network footprint. We are also supervising any IPsec connections now in order to detect broken NAT peers.

Support for Huawei ME909: The Huawei ME909 module is now generally supported. However, voice calls with this modem are not yet supported.
Secure SSL Client Connections: Client applications will now abort connections to servers with an invalid certificate. Trusted CA root certificates can be uploaded to bypass that.
Support for Multipath Routes: Multipath routes are now being supported. They can be used to distribute IP sessions over multiple hosts. In addition, WAN links can be configured as distributed interfaces in order to balance traffic in the same manner.
GRE Implementation: It is now possible to run GRE tunnels. However, we have not yet completely finished compatibility tests to other systems.
Quality of Service: We have implemented a QoS mechanism based on Linux’s advanced traffic control, so that the system is now capable of prioritizing and shaping bandwidth for particular IP services.
VLAN Implemenation: The Ethernet interfaces are now supporting Virtual LAN (VLAN) according to IEEE 802.1P/Q.
