    are you saying you can ping from your pc or that you can ping from the exec prompt in the router? is the e0/0 successfully picking up an ip add?

    what do you get in the o/p from sh int e0/0? and from show ip route?

    Im not sure but think you need the following statement

    Routher#ip nat pool {"name of pool"} {start-ip end-ip} (or) TYPE match-host

    as you have your nat pool from dhcp on the inside!

    you could aslo bind your pool to your outside port e/0/0
    I think also that you need an access list to trigger nat

    #access-list {number permit} {source-address} {mask}
    #ip nat inside source list {access-list} pool {name of pool}

    try show ip nat statistics

    and debug nat ip

    you should get

    05:32:23: NAT: s=>, d= [70]
    05:32:23: NAT*: s=, d=> [70]
    05:32:25: NAT*: s=>, d= [71]
    05:32:25: NAT*: s=, d=> [71]
    05:32:27: NAT*: s=>, d= [72]
    05:32:27: NAT*: s=, d=> [72]
    05:32:29: NAT*: s=>, d= [73]
    05:32:29: NAT*: s=, d=> [73]
    05:32:31: NAT*: s=>, d= [74]
    05:32:31: NAT*: s=, d=> [74]

    sorry could be anymore help not done much with NAT
