   * Network configuration (of 4 x 1 GB/s ethernet ports)   * Network configuration (of 4 x 1 GB/s ethernet ports)
     * Access to public internet modem, via 1 Ethernet port - **the WAN (Wide Area Network) connection**     * Access to public internet modem, via 1 Ethernet port - **the WAN (Wide Area Network) connection**
-      * modem is VDSL based, set into bridge mode to allow connection to control using this machine as router +      * Early 2024 I was upgraded to a full fibre internet connection.  A connection box / modem converts the fibre to RJ45 1GB/s ethernet IP connection inside the house.  The old ISP supplied VDSL modem/router does have a WAN input that works, however the all the ethernet connections are limited to 100Mb/s.  Hence on the 250Mb/s plan this router is not fully suitable for purpose. 
-        * modem is currently set to use direct remote DHCP/IP as specified by ISP (Internet Service Provider requirements), was originally setup using PPPoE. +
-        * There is also as separate static IP address setup to access and control the modem+

The bridge network setup has the following required features:
       * It allows connections of multiple physical Ethernet ports to a bridge interface device, with the bridge effectively acting as a network switch for the connected physical ports.  (On my home server I have 4 x 1GB/s Ethernet ports and an add in PCIe card that provided a 2.5GB/s Ethernet port. All these physical ports are connected to a common network bridge device. This seem to just work, and each physical device seems to operate at its specific capacity.)       * It allows connections of multiple physical Ethernet ports to a bridge interface device, with the bridge effectively acting as a network switch for the connected physical ports.  (On my home server I have 4 x 1GB/s Ethernet ports and an add in PCIe card that provided a 2.5GB/s Ethernet port.
