- freely configurable
Each Ethernet port can be freely configured (LAN, DMZ, WAN, monitor port, off). LAN ports can be operated as a switch or
separately. Additionally, external DSL modems or termination routers can be operated as a WAN port with load balancing and
policy- based routing. DMZ ports can be operated with their own IP address range without NAT

Management
LANconfig
Configuration program for Microsoft Windows, incl. convenient Setup Wizards. Optional group configuration, simultaneous
remote configuration and management of multiple devices over ISDN dial- in or IP connection (HTTPS, HTTP, TFTP). Configuration
program properties per project or user. Automatic storage of the current configuration before firmware updates. Exchange of
configuration files between similar devices, e.g. for migrating existing configurations to new LANCOM products. Detection and
display of the LANCOM managed switches

LANmonitor
Monitoring application for Microsoft Windows for (remote) surveillance and logging of the status of LANCOM devices and
connections, incl. PING diagnosis and TRACE with filters and save to file. Search function within TRACE tasks. Wizards for
standard diagnostics. Export of diagnostic files for support purposes (including bootlog, sysinfo and device configuration
without passwords). Graphic display of key values (marked with an icon in LANmonitor view) over time as well as table for
minimum, maximum and average in a separate window, e. g. for Rx, Tx, CPU load, free memory. Monitoring of the LANCOM

Firwall GUI
Graphical user interface for configuring the object- oriented firewall in LANconfig: Tabular presentation with symbols for rapid
understanding of objects, choice of symbols for objects, objects for actions/Quality of Service/remote sites/services, default
objects for common scenarios, individual object definition (e.g. for user groups)

WEBconfig
Integrated web server for the configuration of LANCOM devices via Internet browsers with HTTPS or HTTP. Similar to LANconfig
with a system overview, syslog and events display, symbols in the menu tree, quick access with side tabs. WEBconfig also
features Wizards for basic configuration, security, Internet access, LAN- LAN coupling. Online help for parameters in LCOS menu

Device Syslog
Syslog buffer in the RAM (size depending on device memory) to store events for diagnosis. Default set of rules for the event
protocol in Syslog. The rules can be modified by the administrator. Display and saving of internal Syslog buffer (events) from

Access rights
Individual access and function rights for up to 16 administrators
User administration
RADIUS user administration for dial- in access (PPP/PPTP and ISDN CLIP). Support for RADSEC (Secure RADIUS) for secure
communication with RADIUS servers.
communication with RADIUS servers.
Remote maintenance
Remote configuration with Telnet/SSL, SSH (with password or public key), browser (HTTP/HTTPS), TFTP or SNMP, firmware upload
via HTTP/HTTPS or TFTP
via HTTP/HTTPS or TFTP
TACACS+
Support of TACACS+ protocol for authentication, authorization and accounting (AAA) with reliable connections and encrypted
payload. Authentication and authorization are separated completely. LANCOM access rights are converted to TACACS+ levels.
With TACACS+ access can be granted per parameter, path, command or functionality for LANconfig, WEBconfig or Telnet/SSH.
Each access and all changes of configuration are logged. Access verification and logging of SNMP Get and Set requests.
WEBconfig supports the access rights of TACACS+ and choice of TACACS+ server at login. LANconfig provides a device login
with the TACACS+ request conveyed by the addressed device. Authorization to execute scripts and each command within them
by checking the TACACS+ server’s database. CRON, action- table and script processing can be diverted to avoid TACACS+ to
relieve TACACS+ servers. Redundancy by setting several alternative TACACS+ servers. Configurable option to fall back to local
user accounts in case of connection drops to the TACACS+ servers. Compatibility mode to support several free TACACS+
implementations

Remote maintenance of 3rd party
devices
devices
A remote configuration for devices behind der LANCOM can be accomplished (after authentication) via tunneling of arbitrary
TCP- based protocols, e.g. for HTTP(S) remote maintenance of VoIP phones or printers of the LAN
