cisco 2514 and dsl (DHCP)

[Guest_imported]

I have a cisco 2514 router, a dsl line which supplies me with one dynamically assigned IP address, and 5 machines running 98,nt, and 2k. I would like to run my dsl line into my router and allow the 5 machines to share the line. I'm pretty sure I need to configure NAT on the ethernet ports, but am a bit unclear on a few areas. First, (these are hypothetical #'s) if my ip address(from provider) is say 4.60.224.74, and my subnet is 255.255.252.0, and my default gateway is 4.61.224.1. How would I configure my two ethernet ports? Port0 will have the dsl line running into it, and the eth1 port will have a connected hub with the 5 machines. Any advice will be greatly appreciated, I've been trying to find an answer for along time now

I believe the correct way to configure it would be to give E0 the ISP's IP (not sure whether or not the router can pull IPs-I don't think so) with NAT enabled, give the E1 an IP that is in your network. That should be a down and dirty. If your not familiar with the CLI for cisco, try downloading the Configmaker software off

Hope that was of some help!

The WAN ip really does not matter at this point. With NAT running all you need is to setup a LAN ip say 192.168.1.1/24 on the ethernet port and use the ip also on your pc's as the gateway with the same subnet. Set ip nat inside on the ethernet and ip nat outside on the serial interface. Then you need this statement

ip nat inside source list 1 interface serial0.1 overload


the serial will be your WAN port out. Then add this

access-list 1 permit any
