Security
WLAN
IEEE 802.11i / WPA with passphrase or 802.1x and hardware encrypted AES,
closed network, WEP64, WEP128, WEP152, access control lists, RADIUS cli-
ent,user authentication, 802.1x / EAP, LEPS
hardware accelerated IPSec-over-
WLAN for optional IPSec encryption of
the radio link
Router, LAN, ISDN
Intrusion detection (IP spoofing, Log-in attempts, portscans), denial-of-service
protection (fragmentation error, SYN flooding, automatic closing of ports/con-
nections). DNS hitlists as well as wildcard filter (URL blocking). High availability
by ISDN dial-backup for Internet access. Alerting by email, SNMP traps and SYS-
LOG. PAP, CHAP and MS-CHAP as PPP authentication mechanisms, password
protected configuration access pro interface, access control list (IP, MAC and
protocol filter) for configuration access and LANCAPI, ISDN dial up number list.
FirmSafe with 2 firmware versions for absolute secure software upgrades.
Firewall
Stateful Inspection, IP packet filter with port ranges; masking (NAT/PAT) of TCP, UDP, ICMP, FTP, PPTP,
H.323,Net meeting, IRC and IPSec; DNS forwarding; inverse masking for IP services out of the intranet
as e.g. web server; support of 2 local networks (LAN plus DMZ); DMZ with own IP address range with-
out NAT.
