Connect a cable modem w/ Cisco 2950

I have a basic question, having a cable modem is it possible to connect it w/ Cisco 2950 using dhcp on the 2950 and distribute to a server and 9 wrkst without a cisco router connected ?

My client has a Linksys broadband router with a firewall buitin after the modem and bought this 2950 that he wants to use.

Thx

You can use catalyst 2950 switch to act as a hub behind the Linksys Broadband router connected to a cable modem..like

PC's.....eth......2950(hub).....eth.....Linksys router.....eth...cable modem......isp

And AFAIK broadband router can act as a dhcp server for those PC's (the internal netowork) and do NAT.

Basically what you saying is the config on the 2950 would be just to enable VLAN 1 and all 24 ports without assigning any IP's, port 1 or 24 for the uplink and the rest of the ports for the LAN on the switch correct?

Preferable I was trying to eliminate the Linksys router since I have a set of 14 usable IP's from the ISP but that didn't work without the Linksys since the ISP router is not manageable.

I was wondering if you could sugest or have a config on the 2950 that I could use for the purpose so I can use a DMZ and a fixed IP for my tftp server as well.

Here is the IP's 65.209.60.17 to 31 mask 255.255.255.240.

Thx so much
