Port Forwarding: Making Computers Accessible from the Internet
FRITZ!Box 3370 43
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.
ESP
GRE
IPv4:
Within IPv4 networks you can open the firewall
for the two protocols ESP and GRE which do not
use ports.
Exposed Host
(Open firewall
completely)
IPv4:
Within IPv4 networks you can open the firewall
for one computer completely. 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 oth-
er computer instead.
IPv6:
Within IPv6 networks you can open the firewall
for each computer completely. These computers
are then no longer protected by the FRITZ!Box
firewall.
