Lesson 49 Cisco Packet Tracer: Building a DIY ISP Network, PPPoE Connection, PAT and ACL Configur...
Did you know how to connect to a provider's network, what a VPN has to do with it, and how to connect a home router to it?
Today we'll look at one of the most common and popular methods of connecting to a provider's network using a PPPoE VPN.
To do this, we'll:
create an address pool that will be assigned to VPN clients;
create a user pool that will connect to the VPN network and receive data transfer services;
tweak a bit of security to prevent any "cold" issues from reaching us, the external network.
This video will also have an addendum where we'll discuss a couple more topics, so stay tuned; it might already be available (by the time you watch).
