Hi Kevin, if you DM me your account/contact details I can get the team to help out. 

When/if you get a new static IP

Do a blacklist check to make sure its not on any blacklists . (it may not matter unless sending email from the sever , but check anyway)
Found that out the hard way & the replacement IP was also on a blacklist . 2 in a row .

https://mxtoolbox.com/blacklists.aspx

You can get static IP add-on for $5 by the way.

Don't think they'll be back.... think they've realized they needed a bit more knowledge behind the complaint/issue. :)

Thank you everyone for the interest and advice. A extra thank you to @michaelmurfy for suggesting pfSense as a solution and many thanks to @Cyril7 for his help with the network configuration.

To exclude the Vodafone Ultra Hub

"All FibreX connections are DHCP. A "static" IP on FibreX is just a reserved DHCP allocation. It's essentially the same thing from the outside looking in (my IP is always 203.xxx.xxx.xxx), but in terms of configuring your router, it needs to be set up to obtain the WAN settings via DHCP." https://www.geekzone.co.nz/forums.asp?forumid=40&topicid=205145&page_no=2

WAN -> VLAN igb3.10 -> DHCP

If you wish to include the Vodafone Ultra Hub for IP Phones:

LAN -> VLAN igb4.10 -> Static

This completes the diagram:

VOIP SIP and UDP Settings

My Ipphones sometimes dropped out after 10+ minutes and unless one used speed dialing a phone number never completed.

None of the above is guaranteed to be correct and complete. The mysql script has been modified to run on mysql 8. Please treat this article as a guide. Any advice or corrections would be much appreciated.
Kevin.
