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
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.
