  1. Alright, new issue.. Help!

    Ok, so im somewhat new at this.. I'll try to explain what im doing..

    Internet(65.x.x.x) -> Firewall (192.168.1.x) -> (192.168.1.4) internal
    Router (192.168.4.x)

    Does this make sense?
    Basically, we have a 192.168.1.x network here, and I am trying to add
    an internal router (linkysys RV042). The WAN of the router is
    192.168.1.4 and the lan is 192.168.4.x

    I have had some success, but its weird. If I set the router in
    'gateway' mode, I can get internet on a computer on the 4.x network
    just fine. BUT, the 192.168.1.x network cannot see the 192.168.4.x
    computer. If i set the router to 'router' mode, I can now see the
    192.168.4.x computer from the 192.168.1.xcomputer (there is a route
    that was setup for me in the managed firewall....). BUT I cannot now
    get internet from a 192.168.4.x machine! HELP!!!!!

    I haven't used routing before. So, you can take my comments or not.

    It sounds like you must set routing mode to 'router.' Then, you must
    configure your router to do the router you require. I suspect that you
    may require static routing, but am not certain. Instructions from
    RV042 user manual follow. Sorry can't be more helpful -- as with
    actual experience with this issue. I began to set up routing once, but
    found a way around it before I had it working.

    Static Routing
    You will need to configure Static Routing if there are multiple routers
    installed on your network. The static routing function determines the
    path that data follows over your network before and after it passes
    through the Router.
    You can use static routing to allow different IP domain users to access
    the Internet through this device. This is an advanced feature. Please
    proceed with caution.
    This Router is also capable of dynamic routing (see the Dynamic Routing
    tab). In many cases, it is better to use dynamic routing because the
    function will allow the Router to automatically adjust to physical
    changes in the network's layout. In order to use static routing, the
    Router's DHCP settings must be disabled.
    To set up static routing, you should add routing entries in the
    Router's table that tell the device where to send all incoming packets.
    All of your network routers should direct the default route entry to
    the Linksys Router.
    Enter the following data to create a static route entry:
    1. Destination IP: Enter the network address of the remote LAN segment.
    For a standard Class C IP domain, the network address is the first
    three fields of the Destination LAN IP, while the last field should be
    zero.
    2. Subnet Mask: Enter the Subnet Mask used on the destination LAN IP
    domain. For Class C IP domains, the Subnet Mask is 255.255.255.0.
    3. Default Gateway: If this Router is used to connect your network to
    the Internet, then your gateway IP is the Router's IP Address. If you
    have another router handling your network's Internet connection, enter
    the IP Address of that router instead.
    4. Hop Count (max. 15): This value gives the number of nodes that a
    data packet passes through before reaching
    its destination. A node is any device on the network, such as switches,
    PCs, etc.
    5. Interface: (LAN, WAN1, WAN2/DMZ) Interface tells you whether your
    network is on the LAN or the WAN, or the Internet. If you're
    connecting to a sub-network, select LAN. If you're connecting to
    another network through the Internet, select WAN.
    Click Add to list to add a route entry or click Delete Selected IP to
    delete the static route entry.
    Click the Save Settings button to save the Routing settings, click the
    Cancel Changes button to undo your changes or click the Show Routing
    Table button to view the current routing table.

    Sounds like your Firewall (192.168.1.1?) address has the wrong netmask
    on it. It shouldn't be able to see the 4.X network in bridge mode,
    if it has the correct netmask.

    Well.. New problem...

    So, I talked to the firewall managers, and they said that they only
    allow 192.168.1.x addresses access to internet, so I got them to open
    that up for the 4.x machines. So now, in 'router' mode (no nat) I can
    get out to the internet!! and the internet can get to me!! yay!

    BUT!!! I still cannot ping a 192.168.1.x machine from the 4.x
    machines. When I ping it, it gets to the 1.x machine, but it never gets
    back to the 4.x machine, any idea why?

    The 1.x machines need to have a static route pointing at the
    4.x network, because the default route is the opposite direction.
