I need to set up two individual private network with two routers

Router1: (got wan-connection)

LAN:
192.168.1.1
255.255.255.0
dhcp range 192.168.1.100-150
dhcp static 192.168.1.129 hw:router:2:xx:bb

Router2 (wired to router1)

WAN settings:
Ip assigned 192.168.1.129
Service provider gateway: 192.168.1.1

Lan:
192.168.0.1
255.255.255.0
dhcp range 192.168.0.100-200

initially this gives both router/network internet-connection and ip-range, but network2 can access network1's computers. I need to make network2 unable to access network one. I cant figure out how to use subnet to do so

    Change the IP of Router 2 to a Static IP on Router 1 and restart both routers. They should not see the other router or be able to access the other computers in normal work. If you wish to more physically separate the networks, change out router 1 (likely) for a good VLAN router and set up an isolated VLAN for router 2. – John Nov 10 '20 at 20:50
  • Thanks, John. Router2 already got a static ip from router1. (192.168.1.129). (I was already thinking of a VLAN-router as plan-b) – putrid Nov 10 '20 at 21:30
  • hi, what's the default gateway set in router2？ – Gloria Gu Nov 11 '20 at 08:14
  • `192.168.0.1` is the LAN gateway on router2 – putrid Nov 11 '20 at 21:11

Do this:

  • Connect one of Router1 LAN ports to Router2 WAN port
  • Enable Router2 DHCP server and set its IP range to 192.168.2.x

The sub-network of Router1 will then use the IP range of 192.168.1.x while the sub-network of Router2 will use 192.168.2.x, where the two will inaccessible one to the other.

  • Ive done exactly that. Router2 will still have access to 192.168.1.x computers. e.g: webserver/ipcam/printer on Router1 – putrid Nov 10 '20 at 21:36
  • Do you mean access to devices directly connected to Router1 such as printer and camera? Is the webserver in question Router1 itself? – harrymc Nov 11 '20 at 07:35
  • I still had access to devices connected to Router1, as printers and camera. (no the webserver was a computer on `192.168.1.x`) I did try change the WAN-ip on Router2 (provided from Router1) to `192.168.2.2` (instead of`*.1.129` as stated) but I was not allowed to use an IP outside the subnetwork of Router1 `*1.x` – putrid Nov 11 '20 at 21:05
