Firewall
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 WANExtended port forwarding
N:N IP address mapping for translation of IP addresses or entire networksN:N IP address mapping
The firewall marks packets with routing tags, e.g. for policy-based routingTagging
Forward, drop, reject, block sender address, close destination port, disconnectActions

Quality of Service
Dynamic bandwidth management with IP traffic shapingTraffic 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 fieldsDiffServ/TOS
Automatic packet-size control by fragmentation or Path Maximum Transmission Unit (PMTU) adjustmentPacket-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

High availability / redundancy
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 updatesFirmSafe
Operation of an external UMTS/HSDPA USB card at the USB host portUMTS backup*
In case of failure of the main connection, a backup connection is established over ISDN. Automatic return to the main connectionISDN backup
Optional operation of an analog or GSM modem at the serial interfaceAnalog/GSM modem backup
Static and dynamic load balancing over up to 2 WAN connections. Channel bundling with Multilink PPP (if supported by network operator)Load balancing
Backup of VPN connections across different hierarchy levels, e.g. in case of failure of a central VPN concentrator and re-routing to multiple distributed
remote sites. Any number of VPN remote sites can be defined (the tunnel limit applies only to active connections). Up to 32 alternative remote
stations, each with its own routing tag, can be defined per VPN connection. Automatic selection may be sequential, or dependant on the last
connection, or random (VPN load balancing)
VPN redundancy
Line monitoring with LCP echo monitoring, dead-peer detection and up to 4 addresses for end-to-end monitoring with ICMP pollingLine monitoring
