Configuring Port Sharing
Overview
With default settings in the FRITZ!Box, programs on your computer
and LAN cannot be accessed from the internet. For applications like
online games and file sharing software, or server services like HTTP,
FTP, VPN, terminal and remote access servers, you have to make your
computer accessible to other internet users.
Port Sharing
Using port sharing you allow incoming connections from the internet.
By releasing certain ports for incoming connections, you grant other
internet users controlled access to the computers in your network.
Port Sharing on Protocols
Port sharing in the FRITZ!Box is possible on the following protocols:
Protocol Internet Protocol Explanation
PING IPv6 The FRITZ!Box responds to ping in-
quiries from the internet addressed to
the IPv6 address of the FRITZ!Box. Ad-
ditionally, you can set up PING6 port
forwarding rules for each computer in
the home network since each comput-
er has its own globally valid IPv6 ad-
dress.
TCP
UDP
IPv4 Within IPv4 networks you can open
the FRITZ!Box firewall for the TCP and
UDP protocols when entering the port
range. One port can be opened for ex-
actly one computer.
