Two Router connected/linked together out of two separate internet connections/customers/providers?

Question

Would it be possible to connect two routers together that are each on their own internet (neighbors internet router connected to our internet router) essentially to just become a networked connection (share files)

Answer 1

If you want to merge your connections you will need a router the supports two internet connections or Dual WAN connections. You would each need to run a connection to that new router from your old router. Their are a couple issues that you would need to work through including IP addresses you both could not be assigning 192.168.x.x addresses in the same subnet to the WAN port as it would mess. You also will have to deal with DNS issues for the file sharing but again this is doable.

Answer 2

Two internet routers on the same network won't work. Those routers are pretty complex pieces of engineering. In addition to being the gateway to the internet, they are also a NAT translator, A DHCP server, and (of course) a router. Putting two of these things on the network would cause massive confusion. The correct way to connect two networks would be to connect them with a bridging router.

Answer 3

No because only one can broadcast the IP's and serve as a gateway or else the network will crash. I would set up a computer as a server and have two wireless nics on it connecting to the two routers and store the files on that server.

Edit:

Upon further contemplation there is a way but it would be really expensive and convoluted.

Answer 4

Not without a third router between. Both home systems are separate networks, and may even be at the same local LAN subnet. Each router would have to be aon different subnets, and a third router could route traffic between the two LANs.
