I have a PIX525 installed with the inside IP for the LAN, the outside IP connecting the Internet Router and a 'new' DMZ IP for a connection to the private IP of a VPN3030.
I tried to ping (extended) from the inside IP of the PIX to the DMZ IP. It couldn't ping, even after I enabled the access-list to allow all IP between the DMZ and the inside interface.
The only thing that I did was putting the NAT to 'use same address' rather than creating a new NAT. Thus, it created the 'Null Rule' to the ACL which I just inserted.
So, what exactly can I do to be able to ping between these 2 interface?
