I have two routers: router A with internet access (DSL cable), and router B acting as a client connected to router A via wifi. Devices are attached to router B via ethernet.
I need to forward some ports to PCs attached to router B. I've set a static route to router B, but router A won't let me forward ports to a different subnet.
What can I do?
I tried to make everything belong to a single subnet with 2 DHCP servers with separate ranges, but it won't work, I think because the static route destination is inside router A subnet.
Shall I use double NAT? Are there other viable solutions?
