!--- For NAT: 

ip nat inside source list 1 interface bvi1 overload

!--- If you have a pool (a range) of public IP addresses provided !--- by your ISP, you can use a NAT Pool. Replace !--- ip nat inside source list 1 interface bvi1 overload !--- with these two configuration statements: !--- ip nat inside source list 1 pool 
          
            overload !--- ip nat pool 
            
             
             
               !--- netmask 
               
               
              
             
            
          


!--- If Internet users require access to an internal server, you can !--- add this static NAT configuration statement: !--- ip nat inside source static tcp 
          
            {80 or 25} !--- 
           
             {80 or 25} extendable !--- Note: TCP port 80 (HTTP/web) and TCP port 25 (SMTP/mail) are used !--- for this example. You can open other TCP or UDP ports, if needed.

ip route 0.0.0.0 0.0.0.0 <default gateway to isp>

!--- For NAT: 

access-list 1 permit 
         
          
           
         

!--- In this configuration, access-list 1 defines a standard access list !--- that permits the addresses that NAT translates. For example, if !--- your private IP network is 10.10.10.0, the configuration of !--- access-list 1 permit 10.10.10.0 0.0.0.255 allows NAT to translate !--- packets with source addresses between 10.10.10.0 and 10.10.10.255.
