NOD 32 Updation

if i want to update NOD32 using Server ( domain ) or Dialup internet connection. is there any option or configuration that will automatically finding server and start downloading.
wen i tried with givin option as select server "automatically", i have to manually enter the server ip and port no to get updated from domain server.

 

Automatically it finds server from its official server list - ESET's servers.
Otherwise , for local update you must enter your address.

Dial-up here (can also be found in the RA Console/Config editor)
