Re: Asus RT-N16 as secondary router, need DHCP on both routers Right now, all 6 wireless cameras have static addresses set up on tomato/Asus settings. 192.168.1.111, *112, *113, etc. Every unique MAC address is assigned it's own IP address.
They have to be static in order to work with multi camera software on laptop and to work through no-ip or similar DNS service, so camera footage can be seen online (away from the house) or on smartphone.
This is the exact setup I have myself at my home, except I am using just 1 router and set up was a breeze.
