LANCOM L-54ag Wireless
Firewall
Stateful inspection firewall Direction-dependant check 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
Masquerading Network Address Translation (NAT), N:N mapping for the translation or masking of IP addresses
Port mapping Provision of services from behind masqueraded computers, for example, to make an internal web server available from the
outside (inverse masquerading)
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
Messaging 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, absolute or connection-related, separate settings for send and
receive directions
DiffServ/TOS Priority packet queuing 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 blockage of login attempts and port scans
IP spoofing Source IP address check on all interfaces: The only accepted IP addresses belong to the previously defined IP network
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
High availability / redundancy
VRRP VRRP (Virtual Router Redundancy Protocol) for non-proprietary 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 freely 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.
