ASA5505 Can't pass traffic between inside (private) & outside (private)

kmartin7564 · ‎08-07-2013

10.15.50.0/24 <---> 10.15.50.254 (inside / ASA5505 \ outside) 10.60.15.253 <---> 10.60.15.254 <--- (cloud) ---> (eventual destination 10.15.60.0/24)

Goal:

10.15.50.0/24 traffic will communicate with 10.15.60.0/24 while block all other. Current config is any/any for troubleshooting.

Example:

10.15.50.249 pings 10.60.15.253 (inside of ASA) and fails. Running it thru ASDM Packet Tracer shows the Outside ASA interface blocking but I have any/any on that interface.

Question:

What am I doing wrong?

Hi,

You can only PING / ICMP an ASA interface from behind that same interface.

So users behind "inside" can PING / ICMP the "inside" interface IP address and users behind "outside" can PING / ICMP the "outside" interface IP address. Users can't PING / ICMP the remote interface from their perspective. The only exception is when users are coming through VPN connection and you use the "management-access " command. But this doesnt apply to your situation.

You seem to be simulating an ICMP send from behind "inside" to the "outside" interface IP address if what you say is true.

So attempt the Packet Tracer using some remote network IP address in the 10.15.60.0/24 network.

You dont seem to have "nat-control" enabled so all traffic should be able to pass through the ASA without translation. So NAT shouldnt be a problem.

You can also add the following configurations

policy-map global_policy

class inspection_default

inspect icmp

inspect icmp error

This ASA is being used to access another ASA across a customer's closed network. Unfortunately the had a missing route in the first hop router that was preventing a ping from 10.15.50.0/24 to 10.60.15.254. One the missing route was added we had connectivity to the other end (an ASA).
