Filter rules can be defined in each profile by collecting category profiles from 58 categories, for example to restrict Internet access to business
purposes only (limiting private use) or by providing protection from content that is harmful to minors or hazardous content (e.g. malware sites).
Clearly structured selection due to the grouping of similar categories. Content for each category can be allowed, blocked, or released by override

Categories/category profiles

Each category can be given an optional manual override that allows the user to access blocked content on a case-by-case basis. The override
operates for a limited time period by blocking the category or domain, or a combination of both. Optional notification of the administrator in case
of overrides

Override

Lists that are manually configured to explicitly allow (whitelist) or block (blacklist) web sites for each profile, independent of the rating server.
Wildcards can be used when defining groups of pages or for filtering sub pages

Black-/whitelist

Timeframes, blacklists, whitelists and categories are collected into profiles that can be activated separately for content-filter actions. A default
profile with standard settings blocks racist, pornographic, criminal, and extremist content as well as anonymous proxies, weapons/military, drugs,
SPAM and malware

Profiles

Timeframes can be flexibly defined for control over filtering depending on the time of day or weekday, e.g. to relax controls during break times for
private surfing

Time frames

Activation of the content filter by selecting the required firewall profile that contains content-filter actions. Firewall rules enable the flexible use of
your own profiles for different clients, networks or connections to certain servers

Flexible firewall action

Response pages displayed by the content filter in case of blocked sites, errors or overrides can be custom designed. Variables enable the inclusion
of current information such as the category, URL, and rating-server categorization. Response pages can be issued in any language depending on
the language set in the user's web browser

Individual display pages (for blocked, error,
override)

As an alternative to displaying the device's own internal response pages to blockings, errors or overrides, you can redirect to external web servers

Redirection to external pages

Automatic notification of license expiry by e-mail, LANmonitor, SYSLOG or SNMP trap. Activation of license renewal at any time before expiry of
the current license (the new licensing period starts immediately after expiry of the current license)

License management

Display of the number of checked and blocked web pages by category in LANmonitor. Logging of all content-filter events in LANmonitor; log file
created daily, weekly or monthly. Hit list of the most frequently called pages and rating results. Analysis of the connection properties; minimum,
maximum and average rating-server response time

Statistics

Messaging in case of content-filter events optionally by e-mail, SNMP, SYSLOG or LANmonitor

Notifications

Wizard sets up the content filters for a range of typical scenarios in a few simple steps, including the creation of the necessary firewall rules with
the corresponding action

Wizard for typical configurations

Simultaneous checking of HTTP traffic for a maximum of 100 different IP addresses in the LAN

Max. users

The SIP ALG (Application Layer Gateway) acts as a proxy for SIP communication. For SIP calls the ALG opens the necessary ports on the firewall for
the corresponding media packets. By using automatic address translation for devices inside the LAN, the use of STUN is no longer needed.

SIP ALG

IP and NetBIOS/IP multi-protocol router

Router

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 interface

HTTP

DNS client, DNS server, DNS relay, DNS proxy and dynamic DNS client

DNS

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 proxy

NetBIOS

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

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