Hi about first question
No it is not a manage router
The set up is
Router… swicht …RJ45 to NUC 11 i5….usb to DAC
Between Swicht and NUC I have a RJ45 to SFP optic and optic to RZJ45
Cables are shielded Cat 8
USB have a filter
ROCK installed in the NUC
Second question
The telephone company did open the port and assigned the IP remotely They told me that doing so the IP remains fixed
That IP and port appears on the display of ARC setting when I open
Sorry I will try tomorrow to incorporate the screen shoot I do not know how to do it now
Those IP and port are the ones I gave to Telephone remote service , I took it from my configuration
I am not acceding to the router,the company recommended me not to do unless I am an expert
Today as I already explained I discover VPzN in my iPhone 13 it was automatically resetting ON but finally I got to take it out
From then I can acces to IRC
But they were some cuts and a message saying week signal!!!
Now seems it is working fine
I will do your other instruction tomorrow
And let you know if everything remains fine
Thsnkd
