Port Forwarding: Making Computers Accessible from the Internet
Setting Up Port Forwarding in the FRITZ!Box
• IPv4: Port forwarding for IPv4 is set up in the “Internet /
Permit Access” menu, on the “Port Forwarding” page.
• IPv6: Enable the advanced view. Port forwarding for IPv6
is also set up in the “Internet / Permit Access” menu, on
the “IPv6” page.
Determining the IPv4 Address for Accessing the FRITZ!Box
If you have enabled ports for forwarding in the FRITZ!Box, oth-
er Internet users can access your computers at the IP address
assigned to your FRITZ!Box by the Internet service provider.
This is a public IPv4 address.
Here is how to determine the public IPv4 address of the
FRITZ!Box:
1. Open any Internet page in order to establish an Internet
connection.
2. Open the FRITZ!Box user interface and enable the ad-
vanced view in the user interface.
3. The FRITZ!Box’s public IPv4 address is displayed on the
“Overview” page in the “Connections” area.
Exposed host
(Open firewall
completely)
IPv4:
Within IPv4 networks you can open the firewall
completely for one computer. This computer is
then no longer protected by the FRITZ!Box fire-
wall. If individual ports are already open for other
computers, then data packets for these ports are
not forwarded to the exposed host, but to the
other computer instead.
IPv6:
Within IPv6 networks you can open the firewall
completely for each computer. These computers
are then no longer protected by the FRITZ!Box
firewall.
