My connection goes like:
ISP -> Modem -> Router A -> Router B -> Computers
The reason why I have two routers is that my modem and my computers are in different rooms and I use router B to bridge the distance between them. Router B is set up as a LAN switch and wireless access point, while router A is set up as a pure gateway.
I'd like to be able to access router A's web interface through router B. Is that possible? Keep in mind that they are in different subnets. (router A: 192.168.9.1; router B: 192.168.0.1) Both routers support port forwarding and routing tables.
