You need a regular 8-10…and more ethernet router that forwards the ethernet jacks. Typically used in offices to differentiate between departments. Look in online stores.
I’m interested in increasing security specifically for entering the administrative panel 192.168.8.1 from the local network. That is, an example of 192.168.0.103 can enter the settings of the router 192.168.8.1, the rest of any addresses cannot.
Perhaps not correctly expressed. It is only about the local network. That is, access to 192.168.8.1 is required only from the local address, for example 192.168.0.5. For all other local addresses, access is closed. There is no question of external access from the Internet, but only a local network.
Access to Gl.Inet admin panel only from local 192.168.0.5 to 192.168.8.1 and no other addresses.
I found a solution in a German forum that helped me to access the Admin Web in my main network.
In the gl inet router, port 80 (TCP) must be opened under firewall - Open Ports Router.
My GL inet router has received the IP 192.168.2.xx from the main network, now I can access the web interface with the IP number.
I hope it helps someone here.
Many thanks for your help.
