modem isp dhcp connect to g0/1 and received dhcp from isp to g0/0

[andohuerta]

Je suis chez un fournisseur d'accès Internet (ISP) qui fournit aussi le service de tv, mon plan est de connecter le modem ISP qui est en DHCP sur le port g0/1 et de connecter un switch qui reçoit directement les adresses DHCP du modem ISP. La raison est que le ISP tv a des adresses multicast que la société refuse de me donner et qui aussi seront plus faciles à configurer donc pour résumer :
Je veux connecter le modem DHCP dans le port g0/1 et envoyer le trafic dans le g0/0 afin que les appareils reçoivent les adresses DHCP du modem ISP,

Hi do you have a basic command where i can check that 

On the link you share i dont see it

Thank you

[balaji.bandi]

This is basic config :

ip routing
!
interface GigabitEthernet0/1
no shutdown
ip dhcp
!
ip route 0.0.0.0 0.0.0.0 gig0/1 dhcp
!

If you like to do NAT

interface Gig0/0
ip address 10.10.10.1 255.255.255.0  (change this what ever you like)
ip nat inside
ip virtual-reassembly in
duplex auto
no shut
!
!
ip nat inside source list 20 interface Ethernet0/0 overload

access-list 20 permit 10.10.10.0 0.0.0.255

!

end
