LANCOM L-54ag Wireless
Scope of features: as of LCOS version 7.5x
Firewall
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
Quality of Service
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.
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
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 EAP- TLS, EAP- TTLS, PEAP, MSCHAP, MXCHAPv2 as EAP authentication mechanisms, PAP, CHAP and MS- CHAP as PPP
authentication mechanisms
WLAN protocol filters Limitation of the allowed transfer protocols, source and target addresses on the WLAN interface
Adjustable reset button Adjustable reset button for "ignore", "boot- only" and "reset- or- boot
IP redirect Fixed redirection of any packet received over the WLAN interface to a dedicated target address
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
Analog/GSM modem backup Optional operation of an analog or GSM modem at the serial interface
Line monitoring Line monitoring with LCP echo monitoring, up to 4 addresses for end- to- end monitoring with ICMP polling.
