Hi, we are setting up an VPN from a PIX router to a Cisco 2800 router. I am following this configuration guide: http://www.cisco.com/en/US/products/hw/vpndevc/ps2030/products_configuration_example09186a008064a06f.shtml
But I'm not sure if I have to this step:
!--- Defines the IP addresses that should not be NATed.
access-list nonat extended permit ip 192.168.1.0 255.255.255.0 172.16.0.0 255.255.0.0
access-list outside extended permit icmp any any
Do I have to no-nat the local net ? They are already being nated outside to reach the internet.
