External access (internet)
The recorder can also be accessed externally by typing
the IP address in the browser’s navigation bar. Since the
recorder is generally not accessible directly from the in-
ternet, you must set up port forwarding on your router.
Accordingly, the router IP address must be entered as
the IP address in the navigation bar when accessing the
recorder via the internet (IPv4). Additional settings are
required for IPv6, which are described in detail below.
The network services on the recorder do not have to be
adapted for access to the web interface on the local net-
work. For external access, you may have to adjust the
default settings of the ports in order to enable access.
The following points are important for remote access:

Using IPv6
Modern internet providers switch what is known as "Dual-
Stack" internet access to the customer's landline connec-
tion. This means that the router provides access to the
internet via both the IPv4 protocol and IPv6. The ABUS
embedded recorder supports both protocols as standard.
Since IP communication for remote connections takes
place between two end points, both subscribers (re-
corder and receiving point) must use the same communi-
cation protocol in order to successfully establish a con-
nection. The IPv6 protocol is not currently widely availa-
ble, so pure IPv6 communication is not practical for the
moment, especially if the receiving point (e.g. the web
browser on a laptop) is mobile and may switch between
IPv4 and IPv6 networks.
Note
As of 2016/2017: IPv6 is currently undergoing
global "roll-out". This means that increasingly
more providers are allowing for IPv6 access to the
internet. Check your internet connection, both on
the recorder and on the intended receiving points,
to take potential limitations and instructions for the
operation of the recorder into account ahead of
time.
We provide the following tips and instructions for setting
up external access to the ABUS embedded recorder,
which take both protocols into account.
Dual-Stack and Dual-Stack Lite (DS Lite)
As part of the global roll-out of IPv6, the IANA stipulated
that internet providers which use IPv6 must also allow
their customers to access the internet via IPv4, in order
to be able to access internet servers/services that are
only available on the IPv4 network. Since the global IPv4
address pool has already been used up, internet provid-
ers that do not have enough ipV4 addresses use an al-
ternative technology known as "Dual-Stack Lite".
Note
Internet connections with "Dual-Stack Lite" have
significant limitations when using IPv4. If possible,
use a provider that employs actual Dual-Stack
technology or ask your provider whether your
Dual-Stack Lite access can be changed to a real
Dual-Stack connection.
Based on the fact that IPv6 is not available everywhere,
we recommend establishing your remote connection via
IPv4 (even with Dual-Stack connections). This particu-
larly applies to mobile networks, which are still in the
process of completely switching to IPv6 on end devices,
with a few exceptions (as of 2016/2017).
Setting up port forwarding (IPv4)
In order for the recorder (web interface) to be accessible
via the internet, the network service ports of the recorder
must be able to be accessed externally using port for-
warding on the router. Set up 1:1 port forwarding on the
router, which opens the HTTP(S) port of the recorder as
well as the RTSP port on the WAN connection of the
router.
Setup differs depending on your router's model. Refer to
the router manufacturer's instructions to find out how to
set up port forwarding on your router.
The rule should be structured according to the fol-
lowing scheme (example):
External HTTP port (on the router): 80
External HTTPS port (on the router): 443
External RTSP port (on the router): 554
Forward to target address:
192.168.0.5 (local IP address of your recorder)
