!!Newbie!!
I'm attempting to set up my first CCNA Lab and here's what I've got.
I have a static IP from Bellsouth DSL.
I have a 2514 with 2 eth and 2 ser ports
The IOS is 11.2 (basically i do not have the option to enter Nat)
i.e. Router(config)#ip nat xxxxx xxxxxx

you can see in the config below I have tried different stratigies to get this connected to the internet

I feel like I'm close, but I'm not sure I can make this happen without upgrading the IOS. any help will be appreciated.

Thanks,
Eric

here is my running config.

The problem you're going to have is that nobody on the public Internet is going to be able to talk to your 172.16.x.x network, since that is private address space. That's where you need NAT. So, you'll be able to send out, but not get anything back.

If you're not able to upgrade your IOS to get NAT, a cheap alternative would be to get a little $30 home router ( or something) to do the NAT for you. Then use the Cisco for routing between that and your internal LAN. That way you can still work with your access lists, etc and play around with it. If your ISP will give you more addresses, then you'll be fine without NAT.

I believe you need an IOS upgrade.

Thanks for the replys I do have a linksys that could translate that for me. But I think I'm just going to bite the bullet and get an IOS upgrade.

Who knows the cheapest place to get upgraded to 11.3 or 12.0?
