    I have big problems trying to get SNMP info through a PIX firewall.

    At our LAN segment, I have setup a Linux/MRTG PC, which I want to read info
    from our Internet router,
    placed at the external interface of our PIX:
    When I try to connect to the router from the MRTG PC, I got nothing.
    I have no problems getting info from switches etc., as long as they are
    placed at
    the same network as the MRTG PC.

    What am I doing wrong ?

    I would suspect that you have permitted the inside IP address to poll,
    but the PIX is translating it to a public IP address. If possible, map
    your graphing server to an open IP address and allow this in your list.
