Vladimir Kuzin Vladimir Kuzin thanks, I found the first mana, but I didn’t find anything like that, and the second one is more detailed, with the help of it I set up that the dsl connection has risen. But packets do not pass through them.
thank you very much, issue resolved

Answer 2

The IES-1000 is a switch, not a modem, and they don't have a wan port. Connect like a switch-to-switch.

Answer 3

Here is a good man with commands and pictures, and here is another one , look for it.
