I am working on a network with 2 routers which are using 2 different IP addresses and assigning different IP addresses to the computers that connect to them. The routers are also connected to each other through cable. All the PC's have internet connection through this setup but I want to change the routers so that they all communicate on the same IP range.
Right now this is what I have:
Cable modem going into a Linksys WRT54G. This WRT54G router has an IP address of 192.168.1.1 (class C subnet) and is set to assign IP addresses starting at 192.168.1.100.
There is also a Linksys Vonage router RT31P2. This is wired to the WRT54G router. The RT31P2 router has an IP address of 192.168.15.1 and is set to assign IP addresses starting at 192.168.15.100.
All devices plugged into either router have internet connectivity but can not communicate to devices connected through the opposite router.
I have a few hours before I have access to the network but this is my plan:
Assign the RT31P2 router an IP address of 192.168.1.2 and to assign IP addresses starting at 192.168.1.200
Is it this simple? Or is there more to it? I don't want to buy any new hardware as I'm pretty sure I can accomplish my end result with what I have currently: 1 network of IP addresses using 2 routers.
