Routing problem

I'm having a problem routing from my home LAB network to the internet.  I can RDP from my home network to my home LAB network without any issues.  I can ping and tracert from my LAB router to the internet, but I can't ping or tracert to the internet from any devices on my LAB network.  tracert from clients die after 192.168.1.1

 

 

  • Problem solved.  Had to turn on NAT on the 2nd router.

       What does "LAB" mean?  "Lab(oratory)"?  "Local-Area Blunder"?  I
    think that I can guess which boxes in the (pretty) diagram are the
    routers, but which subnet is "my home network", and which is "my home
    LAB network"?

       The router with LAN IP address 192.168.1.1 could use a static route
    with:

          Destination: 192.168.2.0
          Subnet:      255.255.255.0
          Gateway:     192.168.1.2
          Metric:      <lowest_allowed>

       Without such a route, when the router at 192.168.1.1 sees a message
    for 192.168.2.x, it would send it to the ISP, just as it would for any
    other foreign (non-192.168.1.*) address.  With that route, it should
    send such a message to the other router (at 192.168.1.2), which should
    pass it to the appropriate destination on its (192.168.2.*) LAN.

       Whether you can get Microsoft Remote Desktop (or anything else) to
    work through two layers of NAT is a different question.

      I already have a static rout in router #1 pointing all traffic to 192.168.2.0 (255.255.255.0) to 192.168.1.2 with a metric of 2 (lowest allowed).
