1. Identification/Inventory of the device
Destination port LAN-Modem: UDP/8513
2. Initialization of the update process
Destination port LAN-Modem: TCP/ 8002
3. Upload firmware
Destination port LAN-Modem: UDP/69 (TFTP)
The previously described automatic processing of the update
requires that any security components (firewalls, routers ...)
used between WuTility and the LAN-Modem allow transparent
communication via these services.

When enabling the listed services in firewalls, routers etc.
various aspects of network security need to be taken into
consideration. These should therefore be run only after
consulting with the responsible network administrator.
Increasing complexity of the network structure brings with it
the risk of transmission problems, so that we recommend only
performing firmware updates from the computer located in the
same subnet as the LAN-Modem.
