Thread: cisco newbie problem

  1. cisco newbie problem

    I have a weird networking problem I can't quite figure out:

    I have a LAN of 10.10.0.0/16. The internal IP (default gateway for
    the hosts) of the firewall is 10.10.0.1.

    I inherited a Cisco1700 w/ 2 ethernet ports and thought I would make a
    quarantined LAB in my cube. I had an existing secondary ethernet
    connection, so I gave the new Cisco1700 an IP of 10.10.0.2. I gave
    the LAB-LAN ethernet interface behind the Cisco an IP of 10.20.0.0/16.

    I put a route on the firewall of 10.20.0.0 255.255.0.0 10.10.0.2.

    There is just one route on the Cisco1700.. 0.0.0.0 0.0.0.0 E0. (Cisco
    Configmaker took care of that).

    From my LAN workstation, I can ping any workstation behind the Cisco.
    however, from any workstation on the LAB-LAN, I can only ping
    10.10.0.1... not any hosts (.25, .26, .27, etc) on the LAN.

    what have I done wrong?

    Not quite clear on the details of each interface and how they are
    physically connected together, but...

    1) Firewall (I assume it is a PIX) should not be used for routing. You
    have a router so let it be the default gateway for each subnet.
    2) may be you can add another route on your firewall to route
    10.10.0.0 traffic pointing to 10.10.0.2
