LAN routing using RRAS and layer 3 switch. Sometimes I can ping, sometimes I can't

    Question

  • I have three servers and one client in 172.16.0.0/16 network and domain vclbevereges.ac.nz and the other three servers and client in 192.168.0.0/16 network and domain opt.com. I have installed RRAS in one server from each network. Let's say Server VCL and Server OPT.

    Yes, both of these servers have two NIC cards,

    For Server A, one NIC(internal network) has been configured as 172.16.1.1/16 (statically assigned) and the other NIC(router end) has been assigned 10.0.0.1/24 (statically assigned).

    For Server B, one NIC(internal network) has been configured as 192.16.1.3/16 (statically assigned) and the other NIC(router end) has been assigned 10.0.0.2/24 (statically assigned).

    All the other servers and clients in vclbevereges domain ( 172.16.0.0/16) have the default gateway set to 172.16.1.1.

    All the other servers and clients in opt domain ( 192.168.0.0/16) have the default gateway set to 192.168.1.3.

    Installed RRAS and configured LAN routing features.

    Configuration of static routing in RRAS

    From Server A(172.16.0.0/16) :

    interface: NIC(router end)

    destination: 192.168.0.0

    network mask:255.255.0.0

    gateway:10.0.0.2

    metric: 256

    From Server B(192.168.0.0/16) :

    interface: NIC(router end)

    destination: 172.16.0.0

    network mask:255.255.0.0

    gateway:10.0.0.1

    metric: 256

    I have connected Second NIC cards of both the servers to Layer 3 switch in random ports.

    I can ping 192.168.1.3 from 172.16.1.1 but not to other servers (192.168.1.1 etc.). Initially I though it is a gateway issue but as I said, I have manually assigned default gateway to 172.16.1.1 to all the servers in 172.16.0.0/16 network and same for the other network ( set default gateway to 192.168.1.3)

    What am I doing wrong here..IS it something to do with cabling? My part of the network is connected to VLAN1 in layer two switch and other part is on VLAN2 . And connection from second NIC going to LAyer 3 switch in random ports.

    When I ping,  sometimes, I get a reply back, sometimes it just says destination unreachable, but no packet lost.

  • Hi,
    To configure the WAN adapter for a dedicated link from a VPN router to an ISP

    1. On the demand-dial router at each site, install the Internet-connected WAN adapter. The WAN adapter is a DDS, T1, Fractional T1, or Frame Relay adapter.

    2. On the WAN adapter’s Internet Protocol (TCP/IP) Properties page, configure the following:

    a. The public IP address and subnet mask allocated to you by your ISP (or by ICANN).

    b. The default gateway of the firewall (if you plan to have the router connect to a perimeter network) or of the ISP router (if you plan to have the router connect directly to the Internet.
    Moer detail please refer the following KB:

    Configure the WAN Adapter

    Hope this helps.
