Port Forwarding: Making Computers Accessible from the Internet
FRITZ!Box 3272 63
11.2 Port Forwarding: Making Computers Accessible from the
Internet
With default settings in the FRITZ!Box, programs on your com-
puter and LAN cannot be accessed from the Internet. For ap-
plications like online games and file sharing software or serv-
er services like HTTP, FTP, VPN, terminal and remote access
servers you have to make your computer accessible for other
Internet users.
Port forwarding rules
Using port forwarding you allow incoming connections from
the Internet. By releasing certain ports for incoming connec-
tions, you grant controlled access to the computers in your
network to other Internet users.
The following port forwarding methods are possible in the
FRITZ!Box:
PING IPv4:
The FRITZ!Box responds to ping inquiries from
the Internet addressed to the IPv4 address of the
FRITZ!Box.
IPv6:
The FRITZ!Box responds to ping inquiries from
the Internet addressed to the IPv6 address of the
FRITZ!Box. Additionally, you can set up PING6
port forwarding rules for each computer in the
home network since each computer has its own
globally valid IPv6 address.
TCP
UDP
IPv4:
Within IPv4 networks you can open the FRITZ!Box
firewall for the protocols TCP and UDP when en-
tering the port range. One port can be opened for
exactly one computer.
IPv6:
Within IPv6 networks you can open the FRITZ!Box
firewall for the protocols TCP and UDP when en-
tering the port range. One port can be opened for
each computer in the network.
