I was issued with a static IP Address on 13th November 2006 by TelstraClear which I  been using within my website up to 5th July 2021 at which time Vodafone forced me to change my IP Address due to billing requirements and their wish to charge me $4.99 per month for the static IP Address.

Three days ago Downer disconnected my TBox and installed a Vodafone TV Box plus a Vodafone Ultra Hub plus a TC4400VDF modem. Downer staff took the cable from my Smoothwall Firewall Server out of the old modem and plugged it into the Vodafone Ultra Hub which is connected to the new TC4400VDF modem. My three landline phones are functioning ok via the Vodafone Ultra Hub. My 3 PCs, Vodafone TV and wifi network are all functioning ok via the Smoothwall Firewall Server. My Webserver can see the Google DNS site via nslookup command but will not function as a website.
Noel Leeming's technician sent by Vodafone was unable to find a solution yesterday.

I have also tried Drupal forum:

Has any other Vodafone residential customer been a static IP Address user? If you are a Static IP Address user please comment on your progress.
