Maybe this is the wrong place to ask this, but I try
My home network looks lake this
First a router connected to Internet 100Mbs fibre
One of the clients to this router is a second router to which I have connected some IoT devices, mostly ESP's.
The second router has its own local network and all its clients are listening to port 80 witch is open
There is a port forwarded on the first router to the second
1. Can a device/client on the second router/network be accessed from the first router/network (internet)
knowing the devices IP on the second network without forwarding any port on that network.
2. Can a device/client on the second router/network access a device on the first router/network
knowing that devices IP on the first network.
Thanks in advance
