We have a class C of our own A.B.C.0 and are currently configuring the
network as follows:

                                      Addresses A.B.C.1 to 15 

  ISP   +-----------+                      +-----------+
  Lease | Cisco     |----------------------| ftp/web   |  plus others
   ---- | 2514      |                      | machine   |  as needed
  Line  |           |----------|           |           |
        +-----------+          |           +-----------+
                               | subnet is A.B.C.16 to 31
                               |
                               | eth0 A.B.C.31
                         +-----------+
                         | Bastion   |     Dual Homed
                         | Machine   |     
                         |           |  
                         +-----------+
                               | eth1 A.B.C.32
                               |
                               | subnet is A.B.C.32 to 254
            -------------------|------------------------       Secure Internal

Can anyone confirm what the netmasks and broadcast addresses should be for the
two bastion ethernet devices.

We are having some trouble agreeing on these.

TIA, Jon
