my isp is 192.168.2.1 i added the modem ip dhcp and made an dhcp but when i want to connect to the ge port well nothing 

i am doing something very wrong and yes i am an beginner

If the WAN Interface is 1GB interface and you connected to ISP 1GB that is ok ?

if the Lan interfce fast ethernet, that is limitation max 100MB,

if you looking 1GB on the Lan side you need to buy different model which has gig ethernet lan side also.

if that answer all your questions, not further assistance required, can we mark as resolved..so in the future if some one has same issue the users can be refer this thread for solution.

Thinking that you have connected your ISP side modem Ethernet connection to Gig 0 - below config should work. :

ip dhcp excluded-address 10.10.10.1 10.10.10.5
!
ip dhcp pool MYDHCP
network 10.10.10.0 255.255.255.0
default-router 10.10.10.1
dns-server 8.8.8.8
!
interface GigabitEthernet0
ip address dhcp
ip nat outside
no shut
!
!
interface Vlan1
ip address 10.10.10.1 255.255.255.0
ip nat inside
ip virtual-reassembly in
!
ip routing
!
access-list 10 permit 10.10.10.0 0.0.0.255
ip nat inside source list 10 interface gig0 overload
ip route 0.0.0.0 0.0.0.0 gig0 dhcp


still not working post new config
==============================
show run
show IP interface brief
show IP route
