Supplementary Software for VPN
All of the information required for a VPN is saved in a configu-
ration file. The terminals involved in any VPN must receive
this file.
Individual computers that are networked over a VPN require a
VPN client.
•
The “Configure FRITZ!Box VPN Connection” Wizard
AVM provides the “Configure FRITZ!Box VPN Connection”
software for creating configuration files. This program is
a Wizard that takes you step by step through the VPN
Configuration software
The configuration files for the VPN connec-
tions are created using a separate program.
The program is provided free of charge and
can be downloaded from the AVM website.
FRITZ!Box user
For FRITZ!Box users who have the right to
access the FRITZ!Box via VPN, no further

configuration. All of the necessary VPN settings, like the
encryption method and access rules, are set automati-
cally. The resulting configuration files must be imported
to the terminals of the VPN tunnel. At the terminal with
the FRITZ!Box the configuration file is then imported to
the FRITZ!Box. The VPN parameters in these files can be
adjusted manually to connect to products by other man-
ufacturers.

The “FRITZ!VPN” VPN client
AVM offers the “FRITZ!VPN” software as a VPN client.
Both the Wizard and the client can be downloaded free of
charge from the VPN Service Portal on the AVM website:

Freely Selectable DNS Servers
DNS servers are preset in the FRITZ!Box for IPv4 and IPv6.
These are the DNS servers assigned by the Internet service
provider.
For both IPv4 and IPv6, the preset DNS server can be replaced
by a free DNS server. Free DNS servers include, for instance,
OpenDNS and Google DNS.
Here is how to change the DNS server entry:
The “DNSv6” page is displayed only if you enabled IPv6 sup-
port for the FRITZ!Box on the “IPv6” page.
1.
Open the FRITZ!Box user interface; see
page 25
.
2.
Enable the advanced view.
3.
In the “Internet / Account Information” menu, select the
“DNS Server” page.
4.
Change the settings for the DNS servers.

DNSSEC: Security for DNS Queries
13.8
DNSSEC: Security for DNS Queries
DNSSEC is short for Domain Name System Security Exten-
sions. As the name says, this is an extension of DNS, the do-
main name system.
DNSSEC ensures that both the DNS server and the informa-
tion returned by the DNS server are authentic, or genuine.
Security with DNSSEC
When a home user surfs the web, she or he sends queries to
the Internet by entering URLs in the address line of the brows-
er. A URL is the name of a website that is easy to remember,
for instance
avm.de/en
. Every query is sent to the DNS server
first. The DNS server resolves the URL into the corresponding
IP address. There is one unique IP address for every URL.
The home user relies on the authenticity of the IP address re-
turned by the DNS server. Authentic means that the response
is the IP address of the desired website, and not a faked IP
address that leads to a fake website. DNSSEC can ensure that
the returned addresses are authentic.
Support with the FRITZ!Box
The FRITZ!Box supports DNSSEC queries over UDP.
The FRITZ!Box has a DNS proxy. The computers in the home
network use the FRITZ!Box as a DNS server. The FRITZ!Box for-
wards DNSSEC queries from the home network to the Inter-
net. The FRITZ!Box forwards DNSSEC responses from the
Internet to the home network. The DNSSEC information must
be validated on the computer in the home network. For this
DNSSEC must be supported in the operating system.

IPv6: The New Internet Protocol
IPv6 stands for Internet protocol version 6 and is the succes-
sor to IPv4.
The FRITZ!Box supports the new IPv6 web protocol and can
establish IPv6 connections:
•
IPv6 support can be switched on in the FRITZ!Box user
interface.
•
For simultaneous use of IPv6 and IPv4, the FRITZ!Box
supports Dual-Stack and Dual-Stack Lite. This means
that the FRITZ!Box can communicate with both IPv4 and
IPv6 domains in the Internet.
•
The FRITZ!Box supports native IPv6 and IPv6 with a tun-
nel protocol. Native IPv6 means that your Internet ser-
vice provider supports IPv6 directly on your line.
IPv6-Capable Services in the Home Network
•
FRITZ!NAS access via SMB or FTP/FTPS
•
Access to the user interface with http or https over IPv6
•
The DNS resolver of the FRITZ!Box supports queries for
IPv6 addresses (AAAA records) and can query the up-
stream DNS resolver of the Internet service provider over
IPv6.
•
The globally valid prefix is distributed via router adver-
tisement.
•
For guest access to the wireless LAN, the home network
and wireless guests are separated by IPv6 subnetworks.
•
UPnP, UPnP AV media server
•
Automatic provisioning (TR-064)
IPv6-Capable Services in the Internet
•
FRITZ!NAS access via FTPS
•
Completely closed firewall to protect against unwanted
data from the Internet (Stateful Inspection Firewall)
•

FRITZ!Box. See the Help available in the FRITZ!Box user
interface for more information.
Configuring IPv6 on the Computer
You can establish connections in the IPv6 range of the Inter-
net only if IPv6 is installed and enabled on the computers in
your home network.
•
IPv6 is already installed and enabled in the Windows 8,
Windows 7 and Windows Vista operating systems.
•
IPv6 has been available in the Mac OS X operating sys-
tems since Mac OS 10.

about location and identity. There are two IP addresses: one
for the location and one for the identity.
The FRITZ!Box can be configured as a LISP router.
•
This chapter address system administrators.
•
It presents a short introduction to LISP.
•
You receive an overview about the possibilities for using
