Yankee,

Thanks for both responses. I hope you dont mind if I ask you a few more questions. I cant tell you how much I appreciate the help. I wont know what ios I have until I get into router. I left another response on the ccna forum.Assuming, my ios version supports dhcp config, with my router it only has one rj 45 etherport, one aui, one serial and wan card slot ( nothing in it now. If I cant use console port then, I wonder if I can use aui, along with 45 port(1 for wan, 1 for lan), or do I have to get a card for another interface. If what I'm saying doesnt make to much sense, its because I dont know what the heck I'm talking about.I just started studying cisco a little while ago, about 2/3 through ccna book, and virtual lab.

Thanks for listening

You can use the RJ45 jack or the AUI, but not both. Since you only have one ethernet interface, you can't route between your home network and your ISP. I don't think the WIC slot will accept an ethenet card, but I've often been wrong before.

I'm a pretty clever guy which means I agree with MadChef!

AUI and RJ45 are either or for the ethernet, but like I said before I'm not familiar with the home use/small office routers. Perhaps a search on the Cisco web page will correct me and the MadChef.

So in IOS's later than 12.1 and on a router with 2 ethernet interfaces you can configure your ISP side ethernet interface to use their DHCP allocated IP address and the other to route to a switch for internal use. IS THAT WHAT YOU ARE SAYING?

Opps soz about the caps.

If you are saying that stated above, how the blazes do you do it? I have scoured the Cisco site for this type of information and found zip. So for my labs I got my ISP to suppliy me a Netgear 4 port Router Switch jobbie. Otherwise I would have used one of my 2514's to do the same job....aaaaaaaaaaaaaaaargh if its true...Phew if its not

Your thoughts and input please.

I think your going to say aaaaaaaaaaaaaaaargh (I didn't count the a's).

Jon,
Yes is the answer!

Any router with 2 ethernet ports would have allowed it. Maybe you should have searched for "routing" or "nat" - just kidding.

You should have asked!!!

A 1605 would do this (all other models allow you to only use one ethernet connection), as would your 2514 but your Netgear has the following advantages -

It was free (although you have to pay for your line rental).
It has a 4 port switch integrated into it for other devices.
It doesn't need transcievers.
Noddy could have configured it.

My friend, search a little harder I have a cisco 1720 with one ethernet port that I am using just fine connected to ISP and LAN. Yes I said one ethernet port!
Some hints it requires the use of 12.1 or above IOS and NAT overload and some knowledge of routing.....
It really isn't that hard. Once you configure it, you will say OH MAN! I should have known that
