firewall interface un-pingable

Hey folks,

I'm working on a FWSM code v3.2(2) in multiple context mode.

I have a context that has several hosts within a VLAN terminated in this context.

I can ping into and out from these hosts.  However, I am unable to ping into the firewall and get a response from the VLAN interface for that vlan..

The hosts can ping the interface, the firewall can of course ping the interface, but from outside, i cannot.

I have configured the following:

ICMP any <interface>

Access-group <acl name> in <interface>

access-list <acl name> permit icmp any any

access-list <outside acl> permit icmp any any

Any thoughts on what is occurring...

Re: firewall interface un-pingable

Bruce,

If you're trying to ping one interface coming in from the other it will not work (not in a basic connectivity set, possible solution is to you management-inside + VPN).

If not, show us the logs on informtion level generated by firewall at time of pinging.
