!--- These commands are needed only on Cisco IOS Software earlier than than 12.2(13)T.

ip subnet-zero
!

!--- 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>
!
interface ethernet0 
 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, 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.


!--- For NAT:

 ip nat inside
 no ip directed-broadcast
!
interface atm0
 no ip address
 bundle-enable
 dsl operating-mode auto
!
interface atm0.1 point-to-point
 no ip address
 no ip directed-broadcast
 no atm ilmi-keepalive
 pvc <vpi/vci>
  pppoe-client dial-pool-number 1
 
!--- Common PVC values supported by ISPs are 0/35 or 8/35.
 !--- Confirm your PVC values with your ISP.

 !
!
interface dialer1
 ip address <ip address> <subnet mask>
 mtu 1492

!--- For NAT:

 ip nat outside
 encapsulation ppp
 dialer pool 1
 ppp chap hostname <username>
 ppp chap password <password>
 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 dialer1

!--- 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 is 10.10.10.0, configure
!--- access-list 1 permit 10.10.10.0 0.0.0.255 in order to allow NAT to translate
!--- packets with source addresses between 10.10.10.0 and 10.10.10.255.
