Hi,

This link will help

It states the following:

Pings Inbound

Pings initiated from the outside, or another low security interface of the PIX, are denied be default. The pings can be allowed by the use of static and access lists or access lists alone.

I dont know the security level of the interfaces. So set the security-level to 100 for inside and dmz interface.

security-level 100

same-security-traffic permit intra-interface

access-group 101 out interface dmz

No, you can only ping from directly connected interface, ie: from outside, you can only ping the outside interface, from dmz, you can only ping the dmz interface, etc etc.

If you are connecting via VPN on the outside interface, you can configure "management-access inside" to be able to ping the inside interface.

However you can only configure 1 management-access line, not multiple lines. Therefore you would need to choose which interface you would like to ping when you VPN in.

Here is the command for your reference:

Hope that helps.
