Problema DHCP

["pacmo@tiscalinet.it" <pacmo@tiscalinet.it>]

Ho un computer che dovrebbe fare da router, proxy server etc non riesco
però a far funzionare il server dhcp visto che i client non riescono a
far nulla
In questo pc ci sono due schede di rete
Per la rete interna
eth0 con indirizzo 10.33.0.200 255.255.255.0
Per il modem ethernet
eth1 con indirizzo 192.168.254.1 255.255.255.0
il modem ha indirizzo 192.168.254.254
ifconfig

Qualcuno può aiutarmi a capire in cosa sto sbagliando ?
Grazie mille
