High availability / redundancy
Optional operation of an analog or GSM modem at the serial interfaceAnalog/GSM modem backup
Line monitoring with LCP echo monitoring, up to 4 addresses for end-to-end monitoring with ICMP pollingLine monitoring
Routing functions
IP and NetBIOS/IP multi-protocol routerRouter
Separate processing of 16 contexts due to virtualization of the routers. Mapping to VLANs and complete independent management and configuration
of IP networks in the device, i.e. individual settings for DHCP, DNS, Firewalling, QoS, VLAN, Routing etc. Automatic learning of routing tags for
ARF contexts from the routing table
Advanced Routing and Forwarding
HTTP and HTTPS server for configuration by web interfaceHTTP
DNS client, DNS server, DNS relay, DNS proxy and dynamic DNS clientDNS
DHCP client, DHCP relay and DHCP server with autodetection. Cluster of several LANCOM DHCP servers per context (ARF network) enables caching
of all DNS assignments at each router. DHCP forwarding to multiple (redundant) DHCP servers
DHCP
NetBIOS/IP proxyNetBIOS
NTP client and SNTP server, automatic adjustment for daylight-saving timeNTP
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, Output
Delay, 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
Layer 2 functions
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
DHCP relay agent information (option 82) can be insterted on devices with WLAN bridge (RFC 3046)DHCP option 82
Router advertisement snopping blocks illegal IPv6 router advertisements in the WLAN bridge. DHCPv6 snopping blocks all illegal DHCPv6 servers.
The lightweight DHCPv6 relay agent (LDRA) can insert relay agent information on layer 2.
IPv6 layer 2 protocol filter
COM port server
COM-port server for the DIN interface. For a serial device connected to it, the server manages its own virtual COM port 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
