Scope of features: as of LCOS version 7.8x
Firewall
Stateful inspection 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)
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
Quality of Service
Traffic shaping
Dynamic bandwidth management with IP traffic shaping
Bandwidth reservation
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
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
Security
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, MS- CHAP and MS- CHAPv2 as PPP authentication mechanism
Anti- theft
Anti- theft ISDN site verification over B or D channel (self- initiated call back and blocking)
Adjustable reset button
Adjustable reset button for 'ignore', 'boot- only' and 'reset- or- boot'
High availability / redundancy
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
ISDN backup
In case of failure of the main connection, a backup connection is established over ISDN. Automatic return to the main connection
Analog/GSM modem backup
Optional operation of an analog or GSM modem at the serial interface
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
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)
Line monitoring
Line monitoring with LCP echo monitoring, dead- peer detection and up to 4 addresses for end- to- end monitoring with ICMP
polling
VPN
Number of VPN tunnels
5 IPSec connections active simultaneously (25 with VPN- 25 Option), unlimited configurable connections. Configuration of all
remote sites via one configuration entry when using the RAS user template or Proadaptive VPN. Max. total sum of concurrently
active IPSec and PPTP tunnels: 5 (25 with VPN 25 Option)
Hardware accelerator
Integrated hardware accelerator for 3DES/AES encryption and decryption
1- Click- VPN Client assistant
One click function in LANconfig to create VPN client connections, incl. automatic profile creation for the LANCOM Advanced
VPN Client
1- Click- VPN Site- to- Site
Creation of VPN connections between LANCOM routers via drag and drop in LANconfig
IKE
IPSec key exchange with Preshared Key or certificate
