LANCOM 1751 UMTS

Scope of features: as of LCOS version 7.2

Stateful inspection firewall

Incoming/Outgoing Traffic inspection based on connection information

Packet filter

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

Extended port forwarding

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

N:N IP address mapping

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

Tagging

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

Actions

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

Notification

Via e- mail, SYSLOG or SNMP trap

Traffic shaping

Dynamic bandwidth management with IP traffic shaping

Bandwidth reservation

Dynamic reservation of minimum and maximum bandwidths, totally or connection bases, separate settings for send and receive 
directions

DiffServ/TOS

Priority queuing of packets based on DiffServ/TOS fields 

Packet- size control

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

Layer 2/Layer 3 tagging

Automatic or fixed translation of layer- 2 priority information (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.

Intrusion Prevention

Monitoring and blocking of login attempts and port scans

IP spoofing

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

Access control lists

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

Denial of Service protection

Protection from fragmentation errors and SYN flooding

General

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

URL blocker

Filtering of unwanted URLs based on DNS hitlists and wildcard filters

Password protection

Password- protected configuration access can be set for each interface

Alerts

Alerts via e- mail, SNMP- Traps and SYSLOG

Authentication mechanisms

PAP, CHAP and MS- CHAP as PPP authentication mechanism

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

Adjustable reset button

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

VRRP

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

FirmSafe

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

UMTS backup

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

ISDN backup

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

Load balancing

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

VPN redundancy

Control of up to 16 redundant VPN gateways for high availability or load balancing

Line monitoring

Line monitoring with LCP echo monitoring, dead- peer detection and up to 4 addresses for end- to- end monitoring with ICMP 
polling.

1- Click- VPN Client assistant
