My setup is as follows.
+-------+ | Modem | +-------+ | | | | | +----> Internet | | | +-------> Router 1 [192.168.1.1] (Home & Private Network) | | | +---> Main PC & Own Mobile Devices | +---> Lightning | +---> Harmony Hub | +---> Wi-Fi Repeater in Bridge Mode for Living Room Devices (No Repeating) | +----------> Router 2 [192.168.2.1] (Guest & Testing Network) | +---> Test & Webbrowsing PC +---> Mobile Devices of Friends and Guests
Is this setup correct so that the devices connected to router 2 are unable to see/connect to the devices connected to router 1 through my modem? I would like to keep my guest & testing network completely out of my private network.
I already checked and both routers have received different public IPs. Also, when I tried pinging my main pc from my test pc, it timed out as desired. However, when I did it the other way around, I got a message from my ISP "TTL expired in transit". What does that mean exactly? Shouldn't it time out like before?
PS: When I connected router 2 for the first time, its internal IP was also 192.168.1.1 but it worked just fine and there was no IP conflict with router 1. Does this mean they were already isolated from the get go? I changed it to 192.168.2.1 just to be sure.
Thanks for any help.
