No.
Almost none of the broadband providers in the US NAT their customers.
Most of them provide a single public IP address to their residential
customers.
Most broadband customers use their own NAT to extend that single
public IP address from the provider to multiple addresses within
the site.
This is a very very different thing from LSN with a lot less breakage.
