LTE-bands

900/2100 MHz

UMTS and HSPA bands

850/900/1800/1900 MHz

EDGE/GPRS bands

+24 dBm

Maximum transmission power UMTS/HSxPA

Receive diversity on the aux antenna (2G + 3G); MIMO (2x2) for LTE (4G)

Diversity support

Incoming/Outgoing Traffic inspection based on connection information. Trigger for firewall rules depending on backup status, e.g. simplified rule
sets for low-bandwidth backup lines. Limitation of the number of sessions per remote site (ID)

Stateful inspection firewall

Check based on the header information of an IP packet (IP or MAC source/destination addresses; source/destination ports, DiffServ attribute);
remote-site dependant, direction dependant, bandwidth dependant

Packet filter

Network Address Translation (NAT) based on protocol and WAN address, i.e. to make internal webservers accessible from WAN

Extended port forwarding

N:N IP address mapping for translation of IP addresses or entire networks

N:N IP address mapping

The firewall marks packets with routing tags, e.g. for policy-based routing

Tagging

Forward, drop, reject, block sender address, close destination port, disconnect

Actions

Via e-mail, SYSLOG or SNMP trap

Notification

Dynamic bandwidth management with IP traffic shaping

Traffic shaping

Dynamic reservation of minimum and maximum bandwidths, totally or connection based, separate settings for send and receive directions. Setting
relative bandwidth limits for QoS in percent

Bandwidth reservation

Priority queuing of packets based on DiffServ/TOS fields

DiffServ/TOS

Automatic packet-size control by fragmentation or Path Maximum Transmission Unit (PMTU) adjustment

Packet-size control

Automatic or fixed translation of layer-2 priority information (IEEE 802.11p-marked Ethernet frames) to layer-3 DiffServ attributes in routing mode.
Translation from layer 3 to layer 2 with automatic recognition of 802.1p-support in the destination device

Layer 2/Layer 3 tagging

Monitoring and blocking of login attempts and port scans

Intrusion Prevention

Source IP address check on all interfaces: only IP addresses belonging to the defined IP networks are allowed

IP spoofing

Filtering of IP or MAC addresses and preset protocols for configuration access and LANCAPI

Access control lists

Protection from fragmentation errors and SYN flooding

Denial of Service protection

Detailed settings for handling reassembly, PING, stealth mode and AUTH port

General

Password-protected configuration access can be set for each interface

Password protection

Alerts via e-mail, SNMP-Traps and SYSLOG

Alerts

PAP, CHAP, MS-CHAP and MS-CHAPv2 as PPP authentication mechanism

Authentication mechanisms

Anti-theft ISDN site verification over B or D channel (self-initiated call back and blocking)

Anti-theft

Adjustable reset button for 'ignore', 'boot-only' and 'reset-or-boot'

Adjustable reset button

VRRP (Virtual Router Redundancy Protocol) for backup in case of failure of a device or remote station. Enables passive standby groups or reciprocal
backup between multiple active devices including load balancing and user definable backup priorities

VRRP

For completely safe software upgrades thanks to two stored firmware versions, incl. test mode for firmware updates

FirmSafe

In case of failure of the main connection, a backup connection is established over the internal LTE modem; automatic return to the main connection

LTE-Backup

In case of failure of the main connection, a backup connection is established over ISDN. Automatic return to the main connection

ISDN backup

Optional operation of an analog or GSM modem at the serial interface

Analog/GSM modem backup

Static and dynamic load balancing over up to 4 WAN connections. Channel bundling with Multilink PPP (if supported by network operator)

Load balancing
