Suppose I have the following configuration:
- Router A: WAN port connected to the Internet, LAN = 192.168.1.0/24
- Computer A: Connected to router A as 192.168.1.101
- Router B: WAN port connected to router A as 192.168.1.102, LAN = 192.168.2.0/24
- Computer B: Connected to router B as 192.168.2.101
Now I want computer A to communicate with computer B seamlessly (e.g. can establish a TCP connection by running nc 192.168.2.101 <port>) by means of routing, rather than merging the two networks into one (which can be easily accomplished using router B as a switch).
Most routers are shipped with NAT turned on, of which I definitely need to turn off in router B. But what other steps do I need to take so that packets from computer A to computer B would go through router B?
I could manually add a routing table entry in computer A so that all packets targeted to 192.168.2.0/24 go through gateway 192.168.1.102, but I would prefer an automatic way if it exist.
