A customer's conference room is too far away from their wireless router and asked if I could set up a 2nd wireless access point so they could connect from that location. "No Problem" I think to myself and proceed to set up an Asus RT-AC66U with Tomato Shibby. I follow some instructions found online to add a guest wireless interface to it and make certain I can access the Internet through it. All good so far.
The next step is to take the router to the customer's location where it will be connected in a slightly different fashion… this is where the problem starts.
The first router has an internal IP of 192.168.0.50 and manages DHCP for that subnet. I give the Tomato router the IP of 192.168.0.49, turned off DHCP and connected one of its four LAN ports to the network. BINGO, everything works great as long as I'm connected to the primary (private) WLAN. Next I connect to the guest wireless network. I receive an IP as expected, but I am not able to access the Internet.
This is where my insufferable lack of gateways and bridges and VLANs all comes crashing down. In this scenario, is there something I can do to allow guest connections access to the Internet?
I tried posting images of my settings screens, but apparently am not allowed to do this as a newb. Can someone sprinkle me with some Karma dust please?
