## tux2

ifconfig eth0 172.16.61.1/24                       # configura o endereço
route add -net 172.16.60.0/24 gw 172.16.61.253     # configura a rota

## tux3

ifconfig eth0 172.16.60.1/24                       # configura o endereço 
route add -net 172.16.61.0/24 gw 172.16.60.254     # configura a rota

## tux4

Neste tux temos de configurar duas portas.

ifconfig eth0 172.16.60.254/24 
ifconfig eth1 172.16.61.253/24

## Transformar tux4 num router
