Hi, first of all let me tell you that i'm a noob with networks and also that English is not my first language. I'll try to explain it with words, but I also have some images

Until now, I've used an old router as a switch (i think) to plug different devices in my room, and then I use a PLC to connect this router to the ISP's in the living room.
To do this, I changed the ISPs router IP from 192.168.0.1 to 192.168.1.1 and my other router to 192.168.1.2
I also opened some ports in the ISP router to my devices and assigned some manual DHCP leases.
This works well, but the ISPs router web interface is crappy and limited and sometimes doesn't work, so I want to restore it to .0.1 and make my router .0.2 on one end ant 1.1 on the other and then put all my devices in .1.0/24
Right now in the LEDE router I have this (just restored it)
Do I have to add another interface or it's ok to just change some parameters in this one?
On the ISP router i have this
(pics 3 and 4, once I can put more than 2 links and 1 image, I'll edit the post)
Could anyone guide, preferably with the web interface?
