Newbie Needs help w/ Local eth network

[<fbrian@nac.net>]

   Hi:

   I have two machines that I want to network via ethernet, using crossover
   cable. (box 1 on eth1  networked to box2 on eth0)


   Box 1  running kernel 2.2.20
   I issued as root

   #echo 1 > /proc/sys/net/ipv4/ip_forward


   eth0 connects me to my gateway to the internet and works fine

   eth1 is where I can't seem to get things correct??

   contents of /etc/network/interfaces/
   # /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)

   # The loopback interface
   auto lo
   iface lo inet loopback

   # The first network card - this entry was created during the Debian
   installation# (network, broadcast and gateway are optional)
   auto eth0
   iface eth0 inet static
           address 192.168.1.2
           netmask 255.255.255.0
           network 192.168.1.0
           broadcast 192.168.1.255
           gateway 192.168.1.1

   auto eth1
   iface eth1 inet static
           address 192.168.3.1
           netmask 255.255.255.0
           network 192.168.3.0
           broadcast 192.168.3.255
           up route add -net 192.168.3.1 eth1

           up route add default gw 192.168.3.1



   Thanks for the help
