    I will be brief and hopefully someone can help. I have a Server 2003 box,
    mulithomed 2 NICs. I have set up RRAS for the LAN config, and on one NIC I
    have a switch with a few nodes and on the other NIC I have another switch on
    the other LAN side. My IP configuration is this NIC 1 has an address of
    192.168.200.5 mask 255.255.255.0 and on the other NIC I have 192.168.1.50
    mask 255.255.255.0 and gateway 192.168.1.1 and they are all /24. I have a
    test box configured on the 192.168.200.0 network with IP configuration
    192.168.200.3 mask 255.255.255.0 Gateway 192.168.200.5 which is the IP of the
    NIC on the RRAS server for that lan. I am unable to ping anything in the
    192.168.1.0 Network here is route print for that box:
    Active Routes:
    Network Destination Netmask Gateway Interface Metric
    0.0.0.0 0.0.0.0 192.168.200.5 192.168.200.3 20
    127.0.0.0 255.0.0.0 127.0.0.1 127.0.0.1 1
    192.168.1.0 255.255.255.0 192.168.200.5 192.168.200.3 2
    192.168.200.0 255.255.255.0 192.168.200.3 192.168.200.3 20
    192.168.200.3 255.255.255.255 127.0.0.1 127.0.0.1 20
    192.168.200.255 255.255.255.255 192.168.200.3 192.168.200.3 20
    224.0.0.0 240.0.0.0 192.168.200.3 192.168.200.3 20
    255.255.255.255 255.255.255.255 192.168.200.3 192.168.200.3 1
    Default Gateway: 192.168.200.5
    However I can ping anything on the 192.168.200.0 network from the
    192.168.1.0 network by adding a route add statement
    route add 192.168.200.0 mask 255.255.255.0 192.168.1.50
    Can anyone help me as to what I am missing here?????

  2. Assuming you have enable IP routing, I would check the Input and Output
    Filters. Or check the NAT/firewall if you enable them.

    NAT and FirewallOpen RRAS>IP Routing>NAT, right-click external
    NIC>Properties>Services and ... 6) IP packet filtering is preventing the
    receiving or sending of IP traffic. ...

    I set up RRAS and NAT is not in the equation. This should be quite simple, I
    am pulling my hair out. This is LAN/LAN routing on W2k3 RRAS. 2 Networks
    192.168.1.0/24 and my new network 192.168.200.0/24...I cannot ping anyting on
    the 192.168.1.0 network from the test host 192.168.200.3. I did a route add
    on the test machine 192.168.1.0 255.255.255.0 192.168.200.5 ....Uggghhhh!
    Still No replies. What am I missing here??? I can ping both sides from the
    RRAS server, and if I add a route add to a node on the 192.168.1.0 side I can
    see the new subnet (192.168.200.0)...why cant anything on the 192.168.200.0
    netowork see anything on the 192.168.1.0 network??? Help Please

  5. I still believe some settings in the RRAS blocks the ping. Try tarcert to
    see where it stop.
