Im really confused about something At home I have a Cisco modem card that supports VDSL 2 which my ISP coming in is a service that supplies it IP addresses through PPPOE and they can change the addresses from time to time how do i do my NAT to allow multiple devices to access the internet at the same time with only one outside IP address that is kind of confusing to me because i cant figure out how to the dynamic Nat with the sources and destination lists what do i put has my outside range? I have provided my current working config with my ISP information not shown this configuration works with one device set to that IP address and the DNS as googles main

Hi @studmuffin
Try this:
no ip nat source static 172.16.100.5 interface Dialer1
access-list 1 permit 172.16.100.0 0.0.15.255
ip nat inside source list 1 interface Dialer1 overload

Hi @studmuffin
To make a NAT PAT you must specify the range of private addresses allowed, which is done through an ACL.
Then, you associate that range (that ACL) with the outside interface (WAN) and overload it.

The access list would act as the the nat pool?
