Can not see my home network across router ports

    Hello everyone..

    I have a 3620 router in my home that I am using to study for my CCNA exam.

    I have 1 ethernet port 'ethernet0/1' connected to a 2924 switch, then my pc (192.168.3.2).
    (e0/0 - Ip address 192.168.1.3)

    I have 1 ethernet port 'ethernet0/0' connected to a 2924 switch, then to my home network.
    (e0/1 - Ip address 192.168.3.1)

    I can not 'see' my home network across the router.
    There is a fully configured DNS/WINS server on 192.168.1.0 network
    ( DNS/WINS server = 192.168.1.101 )

    I have a dlink broadband router feeding the internet to my network.
    It's internal IP is 192.168.1.1

    I installed 'Dude, version 2.2' It located the devices on the 192.168.1.0
    side of the router, but only displayed them after I set the preferences to
    allow it to display items with no services. But it didn't find all of them.

    I can not ping across the router to anything on the other side.
    I CAN get to the router from both networks, but not to the other side's interface

    The results I am trying to get are:
    -- I need to share certain devices between the two networks.
    -- 1 network has a network printer, the other has a networked scanner.
    -- the 192.168.1.0 network has the file server on it. Both networks need access to it..
    -- I don't want them to share anything else.

    I am so totally lost. I added the static route to the 1/0 network, I set the default network.
    I just do not get it.

    Can someone please help?
    Thanks!

    have you configured the DLINK router to know that 192.168.3.0/24 is
    reachable via 192.168.1.3 ???
