Hi

I have a network to configure as follow:

INternet
|
Router
  |
Firewall
  |
MySubNet


Router and Firewall are connected by a Ethernet-Link with only two peers.

Ethernet is a broadcast-type interface,so i need to configure it using a
little as possible subnetmask.
In other word i must configure a subnet with 2 address but using subnetting
i'll need at least 4
IP address 1 for network 1 for broadcast a 2 for hosts.
How is possible to save IP addresses?
Can i use a PPP like configuration for Ethernet MEdia?
Something like :ifconfig ed0 192.168.0.33 192.168.0.34 netmask
255.255.255.255
I tried but.... something goes wrong..

THanks
