I'm having a small problem with a multi-Homed layout.I'm adding a backup
domain controller to a sub net in another building

Current setup:

Four sub-nets

        192.168.1.0, 192.168.2.0, 192.168.3.0, 192.168.100.0

SBS Server as Firewall and DNS (root)

        NIC1 -WAN-

        NIC2 192.168.100.2

W2k Advanced server (2 node)

        Node1: NIC1 192.168.100.3,  NIC2 192.168.1.1,  NIC3 192.168.2.1,
NIC4 192.168.3.1

        Node2: NIC1 192.168.100.4,  NIC2 192.168.1.2,  NIC3 192.168.2.2,
NIC4 192.168.3.2

Cluster Resource Address

                Sub-Net1 192.168.100.5,  Sub-Net2 192.168.1.5,  Sub-Net3
192.168.2.5,  Sub-Net4 192.168.3.5,  Gateway 192.168.100.2

W2k server Domain backup

                NIC1 192.168.1.10

The problem is I can't route through the cluster.

I've tried with and with out RAS, static address and adding routes.

If I turn on NAT I can route through the cluster to the firewall but I can't
route from the firewall to the terminal.

I'm sure I'm missing some thing stupid.

Any help would be much appreciated.

Thanks Carter L. Howard

   IP routing assumes that machines with addresses in the same subnet are on
the same segment, and expects to be able to communicate at the network level
(MAC addresses). So you cannot route packets, you have to have a bridge or a
point-to-point link. W2k does not support bridging, so I think your best bet
would be a VPN connection through the WAN.

    This would give you a PPTP connection, and if this point-to-point
connection has 192.168.1.x addresses at both ends, the server will do proxy
ARP and intercept LAN traffic for the remote and forward it over the
point-to-point link.

Hi,

    I have a WinNT domain on a LAN and  a couple of machines behind another

that is blocking out EVERYTHING and we'd like to see the machines on the

thanx
