I need someone with knowledge in networking to solve this task and break the steps for me. This is so important to me, but I can't find a good source of information. Task: "I have two routers running DDWRT firmware (after market firmware) and I have one internet modem. I need to daisy chain the two routers together. The internet modem gateway IP address that plugs into the WAN port of our router is 192.168.0.1 for local PAN (personal area network). One router that will hold private data call is POS router. The other router will just be a free internet access for the shop. Knowing this information, how would you setup the system and what network IP's would go where on each interface. Note that each router has 1 wan port and 4 switch ports."
Thanks in advance for your help.
