connecting a modem/router (can't disable) Dhcp to a cisco router (want to enable Dhcp)

[Reprovoid]

HI.I want to connect my speedtouch modem router to a cisco router and enable DHCP on the router.The problem Is I can't disable DHCP on the speedtouch.There Is no option to do this.

I assume connecting the speedtouch to a consumer routers wan port would not allow DHCP on the speedtouch to get through.How can I achieve this on a cisco router?
Thanks.

Hi,

why don't you just configure the interface connected to modem to get its ip address with dhcp from modem  with the interface command: ip address dhcp  ?

Hi.The reason Is I want to enable DHCP server services on the router for practice purposes.

If I do as you say wont the Interface connected to the modem/router receive an Ip address In the DHCP pool of the modem/routers lan Interfaces ?

Hi,

No, you can put the interface to modem as dhcp client and the interface to LAN as server.

To give out a dhcp address you need to receive a request from a client and the modem is not going to do that.
