!--- For DHCP:


ip dhcp excluded-address <ip address of ethernet0>
ip dhcp pool <dhcp pool name>
 network <ip network address of ethernet0> <subnet mask>
 default-router <ip address of ethernet0>
 dns-server <ip address of dns server>

 no shut 
 ip address <ip address> <subnet mask>
 ip tcp adjust-mss 1452
 
!--- If the ip tcp adjust-mss 1452 command is not supported, 
 !--- try this configuration statement:
 !--- ip adjust-mss 1452   


 
!--- If this command is not supported in your current Cisco DSL Router software
 !--- release, either upgrade to the latest Cisco DSL Router software or follow the
 !--- procedure in the "Possible Required Configuration Steps on the PC"
 !--- section of this document.

 pvc <vpi/vci>

!--- Common PVC values supported by ISPs are 0/35 or 8/35.
 !--- Confirm your PVC values with your ISP.

 ppp pap sent-username <username> password <password>

!--- For NAT:


ip nat inside source list 1 interface dialer1 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 dialer1 overload

 

!--- with these two configuration statements:
!--- ip nat inside source list 1 pool <nat pool name> overload
!--- ip nat pool <nat pool name> <first ip address>
!---  <last ip address> netmask <subnet mask>




!--- If Internet users require access to an internal server, you can
!--- add this static NAT configuration statement:
!--- ip nat inside source static tcp <inside ip address of server> {80 or 25}
!---  <outside well-known ip address of server> {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 classless
ip route 0.0.0.0 0.0.0.0 interface dialer 1


!--- For NAT:


access-list 1 permit <ip network address of ethernet0> <wildcard mask>

!--- 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 was 10.10.10.0, configuring
!--- access-list 1 permit 10.10.10.0 0.0.0.255 would allow NAT to translate
!--- packets with source addresses between 10.10.10.0 and 10.10.10.255.
