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
internet, you must set up port forwarding on your router.
As such, you have to enter the router IP address in the
address field for access 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
network. 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:

Notes on using IPv6

Setting up port forwarding on your router

Required ports for remote access to the web
interface: HTTP(S) and RTSP

Free DDNS service from ABUS: ABUS server

Access to DS Lite connections
Using IPv6
Modern internet providers switch what is known as
"Dual-Stack" internet access to the customer's landline
connection. 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 (recorder and receiving point) must use the
same communication protocol in order to successfully
establish a connection. The IPv6 protocol is not currently
widely available, 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
2018 status update: IPv6 is currently undergoing
global "roll-out". This means that increasingly
more providers are allowing for IPv6 access to
the internet (status update Q1 2018: 35% of all
German connections). 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
providers that do not have enough ipV4 addresses use
an alternative 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 particularly applies to mobile networks, which are
still in the process of completely switching to IPv6 on
end devices, with a few exceptions.
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
forwarding 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
following scheme (example):
External HTTP port (on the router): 80
External HTTPS port (on the router): 443
External RTSP port (on the router): 554
