Lancom Systems OAP-3G 61539 Benutzerhandbuch

LANCOM OAP-3G

Scope of features: as of LCOS version 8.5x

Supported standards

UMTS, HSPA+ (HSPA+ with up to 21 Mbps, HSUPA with up to 5.76 Mbps), Edge, and GPRS support

UMTS and HSxPA bands

850/900/1900/2100 MHz 

EDGE/GPRS bands

850/900/1800/1900 Mhz (EDGE up to max. 236kbps)

Diversity support

Receive diversity on the aux antenna

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

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. Bandwidth control and QoS also for UMTS connections

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

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. Extended functionality with Content Filter Option

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, MS- CHAP, MS- CHAPv2 as EAP authentication mechanisms, PAP, CHAP, MS- CHAP and MS- CHAPv2 
as PPP authentication mechanisms

Network protection

Network protection via site verification by GPS positioning, device stops operating if ist location is changed.

IP redirect

Fixed redirection of any packet received over the WLAN interface to a dedicated target address

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

Load balancing

Static and dynamic load balancing over up to 2 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
