I am trying to setup a point to point IPsec VPN between a PIX 525 and ASA 5520. I am not familiar with firewalls and have been studying up at this point. I am reaching out to gain knowledge from the experts, not simply the solution. I have installed GNS3 with a PIX version 7.2(4) and ASA 8.4(2) to assist me with practical application.
I've found some guidance online with the commands however, I more interested in knowing the reasoning behind the commands in order to completely understand the process in setting up the VPN and specifically what's different in the process between the PIX and ASA.
If anyone could guide me through the process with reasoning behind the steps, I would greatly appreciate it. Thanks!
