Port Forwarding: Making Computers Accessible from the Internet
FRITZ!Box 7490 87
Can Always Be Reached, Even When the IP Address Changes
Every time the Internet connection is interrupted, the Internet
service provider re-assigns the IP address. The IP address
may change in the process. Therefore it is a good idea to use
MyFRITZ! or dynamic DNS so that the IP address can always
be reached under the same name. For more information
about MyFRITZ!, see the chapter MyFRITZ!: Accessing the
FRITZ!Box from Anywhere on page 70. For more information
about dynamic DNS, see the section Dynamic DNS: Name
instead of IP Address on page 88.
