I did not know that with sme that you could eliminate the modem?
Yes, you are correct I would love a more simple way any instructions would be helpful (KISS)
Modem is essential, set to bridged mode so all it does is the link, authentication is done by the server.
You didnt describe your current setup..below is my old setup, server-gateway mode with modem bridged
Modem, just does the job of moving the electrons, Server has two nics, First connected to modem and will have the public static IP and a second that provides local DHCP and services to the internal network and can have an ip in range 192.168.x.x (or whatever youy decide for the internal lan)
line in - -> Modem -> Server -> home network
On a FTTN if I do above I lose voip. once bridged the modem is no longer accessable from the network, it is just a dumb port
Sticky point with NBN, most ISPs provides own modems, some lock them and/or prevent use of your own, some allow you to dig around and set as needed, I am not with optus, but with iiNet and can bridge supplied modem or use my own.
Have a read through the whirlpool forums there are threads on all isps, modems etc and what can or cannot be done...

Optus
IPoE (DHCP)
No login required
First connection must be done with Optus supplied modem
After that, can switch to BYO modem but MUST copy Optus Modem VDSL MAC Address to your modem MAC – Most modems support this feature. (Certainly the el-cheapo TP-Link TD-W9970 does)
So dunno, suggest you do some reading of whirlpool the info will be there
