  1. Hi Keith, 13.0.0.1 is the NAT address for 172.16.0.2 right? IPsec configured on the router encrypts whatever data sent between the configured ip’s(B/W 172.16.0.0/24 AND 192.168.0.0/24 in this video)please correct me if i am wrong. THANKS sir.

  2. I don’t get it with the source ip adresses. The router would change the source private ip address anyway if it is ipsec or not if it goes through the internet. It also encapsulates the whole packet with HDLC or whatever protocol the router is using to connect to the ISP router. No one could ever see the private ip address even if ipsec is not used. Could you please elaborate on that one?I really don’t get it
