I'm trying to link two Cisco routers with a static route and I haven't been able to get it working as expected.

Here is the basic setup:

  • Router 1 - WRV210 - 192.168.1.1 - connected to cable modem
  • Router 2 - RV120W - 192.168.2.1

I already have several machines on Router 1 that are working and I want to setup Router 2 with a few other machines on the different subnet.

Here is what I've configured:

  • Connected the WAN port on Router 2 to a LAN port on Router 1
  • Configured Router 1 to give 192.168.1.2 to Router 2 via DHCP
  • Configured Router 1 with a static route (192.168.2.0 mask 255.255.255.0) to 192.168.1.2 using the LAN & Wireless interface
  • Disabled the firewall on Router 2 (since it is covered by Router 1)
  • Configured Router 2 to "Router" mode instead of "NAT" mode
  • Configured Router 2 with a static route (192.168.1.0 mask 255.255.255.0) to 192.168.1.1 using the WAN interface

From the research I've done I think that should be enough but things aren't working exactly as expected:

  • Router 2 can ping 192.168.1.1 and 192.168.1.101 (a machine on router 1)
  • A machine on Router 2 can ping 192.168.1.1 and 192.168.1.101 (a machine on router 1) ping 192.168.1.1 and 192.168.1.101 (a machine on router 1)
  • Router 1 can NOT ping 192.168.2.1 or 192.168.2.101 (a machine on router 2)
  • A machine on Router 1 can NOT ping 192.168.2.1 or 192.168.2.101 (a machine on router 2) can NOT ping 192.168.2.1 or 192.168.2.101 (a machine on router 2)
  • Router 1 and a machine on Router 1 can ping 192.168.1.2 (Router 2 itself)

I'm confused as to why Router 1 cannot talk to the 192.168.2.0/255.255.255.0 subnet. Any help would be greatly appreciated.
