NTP client and SNTP server, automatic adjustment for daylight-saving time

NTP

Policy-based routing based on routing tags. Based on firewall rules, certain data types are marked for specific routing, e.g. to particular remote
sites or lines

Policy-based routing

Dynamic routing with RIPv2. Learning and propagating routes; separate settings for LAN and WAN. Extended RIPv2 including HopCount, Poisoned
Reverse, Triggered Update for LAN (acc. to RFC 2453) and WAN (acc. to RFC 2091) as well as filter options for propagation of routes. Definition
of RIP sources with wildcards

Dynamic routing

DHCPv6 client, DHCPv6 server, DHCPv6 relay, stateless- and stateful mode, IPv6 address (IA_NA), prefix delegation (IA_PD), DHCPv6 reconfigure
(server and client)

DHCPv6

VLAN ID definable per interface and routing context (4,094 IDs) IEEE 802.1q

VLAN

Packets sent in response to LCOS service requests (e.g. for Telnet, SSH, SNTP, SMTP, HTTP(S), SNMP, etc.) via Ethernet can be routed directly to the
requesting station (default) or to a target determined by ARP lookup

ARP lookup

Automatic discovery of network topology in layer 2 networks (Link Layer Discover Protocol)

LLDP

COM-port server for DIN and USB interfaces. For multiple serial devices connected to it, the server also manages its own virtual COM ports via
Telnet (RFC 2217) for remote maintenance (works with popular virtual COM-port drivers compliant with RFC 2217). Switchable newline conversion
and alternative binary mode. TCP keepalive according to RFC 1122 with configurable keepalive interval, retransmission timeout and retries

COM port forwarding

Host port for connecting USB printers via RAW-IP and LPD; bi-directional data exchange is possible

Print server (USB 2.0)

ARP, proxy ARP, BOOTP, LANCAPI, DHCP, DNS, HTTP, HTTPS, IP, ICMP, NTP/SNTP, NetBIOS, PPPoE (server), RADIUS, RIP-1, RIP-2, RTP, SIP, SNMP,
TCP, TFTP, UDP, VRRP

IP

NDP, stateless address autoconfiguration (SLAAC), stateful address autoconfiguration (with DHCPv6), router advertisements, ICMPv6, DHCPv6,
DNS, HTTP, HTTPS, PPPoE, TCP, UDP

IPv6

IPv4/IPv6 dual stack

Dual Stack

WEBconfig, HTTP, HTTPS, SSH, Telnet, DNS, TFTP, Firewall

IPv6 compatible LCOS applications

PPPoE, Multi-PPPoE, ML-PPP, PPTP (PAC or PNS) and IPoE (with or without DHCP), RIP-1, RIP-2, VLAN, IP

Ethernet

1TR6, DSS1 (Euro-ISDN), PPP, X75, HDLC, ML-PPP, V.110/GSM/HSCSD

ISDN

IPv6 over PPP (IPv6 and IPv4/IPv6 dual stack session), IPoE (autoconfiguration, DHCPv6 or static)

IPv6

6to4, 6in4, 6rd (static and via DHCP)

Tunneling protocols (IPv4/IPv6)

ADSL1, ADSL2 or ADSL2+ with external ADSL2+ modem

xDSL (ext. modem)

UMTS/HSDPA with external module at the USB interface

UMTS/HSDPA* (ext. module)

ISDN data or voice usage via internal ISDN interface

ISDN

Analog or GPRS operation via serial interface

Analog/GPRS (ext. modem)

A UMTS USB modem is not supplied. Supported UMTS USB modems at www.lancom.eu/umts-support

*) Note:

10/100/1000 Mbps Gigabit Ethernet

WAN: Ethernet

4 individual 10/100/1000 Mbps Ethernet ports; up to 3 ports can be operated as additional WAN ports with load balancing. Ethernet ports can be
electrically disabled within LCOS configuration. The ports support energy saving according to IEEE 802.3az

Ethernet ports

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
