TechChange Migration
Important information for the migration
• The new VDSL router will contain your own specially adapted basic configuration with an
xDSL user name and password. This will ensure that you can get online again with VDSL
and you will retain any usual fixed IP addresses.
• All other settings, such as wireless and firewall settings, will have to be reconfigured by you
or your IT partner. It is therefore recommended that you document the settings of your
ADSL router prior to the migration.
Use case 2 (with web services, without VPN)
• It is particularly important that the settings for your web services (e.g. web or mail server)
are correct as you will no longer be able to access them if they have not been configured
or the configuration is incorrect.
Use case 3 (with VPN)
• It is particularly important that the settings for your VPN are correct, otherwise your
branches or remote access users will no longer be able to communicate with one another.
If you operate web services (e.g. web or mail server), the settings of use case 2 are also
important, of course.
