Hmm - let me try, dkryder.
My router is a fritzbox 7490.
It is delivered from my ISP, preconfigured to their servers.
The router is setup with an external facing fixed public IP addr. and an internal 192.168... network.
I can setup my internal devices by either taking their MAC addr. (but can't do that with the rock64, as the MAC changes on every boot, and my ISP told me that I can only enter MAC addresses for internal device IPs) and enter it into the routers Home Network, allocating it a fixed internal IP - or I can just let a device connect to the router and it is automatically given an IP via the routers DHCP service.
On top of that I have several other public fixed IP addresses, which my ISP has setup on the router. Those addresses are on another netmask and gateway IP.
Those are the IPs I wish to use for the rock64.
When I connect a rock64 to the network they obviously are allocated an internal network IP.
I want to allocate them one of my external public fixed IPs, so for that to happen I need to baptize the rock64 itself in the /etc/network/interfaces by entering eth0 as static and add address, netmask and gateway manually - as well as entering 2 dns-nameservers in the /etc/resolv.conf. (this procedure I have done for years without any issues.)
So that's where I have to give up, as those files are not responding with my entries when rebooting. Hence my comment about where everything has moved
Somewhat confused, I admit.
..oh, and that's where my further confusion sets in:
When I login to a rock64 via the GUI and open up Edit Connection - I can enter (on the IP4 tab) external fixed IP, netmask and gateway - plus 2 nameservers.
After reboot all this is showing correct in Connections Information.
OK - I'm thinking - so I go to /etc/network/interfaces and see that the entries I made on the IP4 tab are not there, which I would have thought.
Looked in /etc/network/interfaces.d/eth0 - nothing there either - just the default entries: allow-hotplug eth0 and iface eth0 inet dhcp
This is why I'm thinking: where has the GUI network manager entries from the IP4 tab gone?
