Hi halijenn / experts
What will happen if on the outside of ASA , Proxy ARP is disabled .I know that with the Static and Global configured , the firewall will Proxy ARP (with its own MAC on behalf of Inside Public servers ) when a packet is coming from Outside world to inside .
Please go through below link which will tell to disable the Proxy ARP in certain scenario
Request to please explain the exact packet flow when the Proxy ARP disabled
Yes the destination MAC will be ASA's inside mac but that doesn't mean the ASA is proxy arping for google's IP address.
The layer 3 device on the inside may receive this packet destined to google from the inside PC and may look in its routing table and may find the ASA's IP as its default gateway and forward the packet onto the ASA.
Unless you change google's ip address with this command
static (outside,inside) 10.10.10.1 76.x.x.x
then the inside interface will proxy arp for 10.10.10.1 and you need to issue http://10.10.10.1 to load google.com on the inside PC.
Now, if you turn off proxy arp then, the PC will not be able to load google.com by issuing http://10.10.10.1. You would have hard code a static arp on the inside router mapping 10.10.10.1 to ASA's inside interface MAC address.
