Replacing ISP provided fiber router with Gargoyle

[ispyisail]

Hi all

In New Zealand, the telecommunications industry has been deregulated for many years. For us, this means physical hardware and data providers have to be mostly separate companies (except cell phone data)

One company installs, owns, and maintains the fiber connection

Another company provides data and internet services (this is the customer contact.)

The fiber gets installed. The customer can choose any ISP they like but the modem/routers are locked to their networks.

It appears that part of this locking is the use of VLANS

I didn't understand how this really worked so for many years I've been double and in some cases triple NATING Gargoyle routers.

It has come to my attention that you can replace the ISP-provided routers with Gargoyle routers with some VLAN knowledge.

No fully tested but I think I have worked out how to do the first part of the tagging VLAN

For bonus points, I've got to work out how to untag a VLAN for the phone

This was my work setup for many years
