Re: Public IP assign to Lan interface

That could be for a few different reasons. They assume you have a Network
filtering device, or that's how they allocate IP space to each customer.

Most
providers have a standard where they use a /30 for the PE-CE relationship, and
then one of your usable IP's to the customer handoff side of the circuit and
make that subnet routable to the CE.

Public IP assign to Lan interface
  

Hi All,

Quick question, why ISP ask the
customer to assign the public IP address to
his LAN interface?

What is the
reason behind it? What I would like to understand the back end
setup of ISP in
such situation?
